going to jump right in and offer my own response.
I'm not making any bets on the future of Amateur Radio today, other than if
it has a future, it's future is digital.
I'd personally like to see what I've wanted to see happen for more than a
decade, a radio based *alternative* to the Internet. Charles and I might
disagree on what the best way is to get there, but I think we share that
vision.
I'd love to be able to equip my car, or my person, with sufficient radio and
computing hardware that I can establish reasonable speed IP based network
connections with other hams (and perhaps with non-hams) from any point on the
surface of the planet.
I think the packet radio experience has demonstrated that VHF/UHF/++ are
perfectly technically feasible for building terrestrial radio networks but
that it requires levels of commitment and cooperation to actually build
anything useful that it's practically quite a difficult job (without an
enthusiastic, wealthy and autocratic sponsor).
I'm personally going to be turning my attention to digital comms on HF. I
think
that's got to be a direction to move to get out of th existing rut. IP/Pactor
perhaps, I don't know.
The Internet experience is something we should leverage off: give the people
a network and they'll find uses for it. Supplying applications without a
network to support them is a waste of time.

It's been a week. He will respond now that you have. He doesn't like to
be first, but rather comments on others comments.

If (and that's a big if) the satellite makes it to its design orbit, then hams
will
have what they need to bypass the thousands of terrestrial stations needed,
and have something more reliable and faster than HF could provide.
I' like to see more ARRL support for microsats, but they've bet the store
on the 3 year old phase-3 attempt.

Ok, I'll bite, but my opinion on this matter is no better than anyone
else's. We all have opinions, and we all have dirty socks in the laundry.
These generally stink, as we all know.
When looking at this, I prefer to separate the "practical" from the
"experimental". The practical stuff will see widespread use; The
experimental stuff probably won't, by it's nature. (complicated, expensive,
limited utility, and so on.)
I'll stick with the "practical" stuff here. (As I see it.)
1. Large-scale VHF/UHF networks, previously and currently administered and
funded as if they were repeater organizations (USA) will come back in a big
way. It is now possible to start seriously considering a national VHF/UHF
net here in the USA. The following URL gives a few clues as to how this will
be accomplished. Unfortunately, I haven't had time to update this page in a
while, but still it contains enough info to get the general idea across.
http://www.texoma.net/~n5pvl/serious.htm
2. Point-to-point HF forwarding of @WW packet bulletins will give way to
multicast distribution which makes much better use of a lot less spectrum.
The present point-to-point stuff (PACTOR, CLOVER, etc.) will still move
personal mail and regional bulletins. (@ALLUS, @EU, @TEXAS, etc.) and
possibly update requests/replies for @WW stuff missed from multicasts for
one reason or another.
http://www.texoma.net/~n5pvl/multi.htm
3. SKYWARN stuff will go over from voice (repeaters) to digital, with each
report automatically including position info via APRS for both the spotter,
and the vector from his position to the weather event being reported. The
weather events themselves will be displayed on the maps as the system is
developed and tweaked over the years. Yes, I know about doppler radar doing
the same thing already, but regional doppler radar is not available in all
locations, and won't be for some time to come.
Regional and a national SKYWARN APRS display(s) (web-site) will show these
WX spots in real-time, automatically making the information available to
NWS, FEMA, local government folks, researchers, and interested individuals.
This will go far in proving the worth of Ham Radio to anybody clever enough
to access a web-site. Great PR, lives saved, and on an ongoing, daily basis.
4. Voice repeaters will still be around, but will slowly change over to
digital as opposed to the analog stuff currently in use. Video and data will
be available for those not busy driving a vehicle.
5. AMSAT will come into it's own soon after RLV's (reusable launch vehicles)
come into common use, cutting the cost of lifting equipment into orbit by a
factor of ten or more. Still, AMSATs will have a hard time making a real
impact on the total volume of traffic moved for quite some time to come.
For the next few decades, I'd be pleasantly surprised to see AMSAT be
anything more than an experimental setup used on a token basis as it is
today.
6. Internet gateways will come into their own as more clever and less
self-defeating applications for them develop. The "LandLine Lid" phenomena
will slide off into the obscurity it deserves.
7. Applications utilizing data telemetry (beyond APRS) will become very
popular. APRS is just the tip of the iceberg concerning the use of telemetry
in digital Ham communications. Eventually, we may see Hams working with NASA
