Luc...I would add this.
What is firmly missing in the amateur satellite effort is something "repeatable" that encourages solid commercial gear to be available to people who want to use the sats.

With respect, I wish once again to take issue with your view that there is a dearth of both useful satellites and of commercial equipment. Previously, you have represented this as a sort of negative feedback loop, with useful satellites (and I understand to you this means those equipped with SSB/CW linear transponder) dwindling in number while commercial equipment becoming more scarce.
I would contend that on both sides you are incorrect. On the equipment side, we have the IC-910H and the new all-in-one Icom rig, over which this list has drooled. I myself use the TS-2000 with great enjoyment. Sure, there are other models that have come and gone, but price-for-performance, we're in satellite appliance-operator heaven these days. (An aside for anyone new to this work who already has an all-in-one rig that will work 144 and 435 in SSB and CW: another option these days is to buy a second-hand FT-817 and, with clever use of computer control you can have full doppler tuning with this arrangement.)
It is going to take about the same thing for hamsats...and one of those is a continued supply of hamsats which encourage more communicating and less experimenting....
Setting aside the contention that communication is the basis of this branch of the hobby, note that we do have a very healthy assembly line of LEO SSB/CW birds: KiwiSat's website has videos of them milling their spaceframe, and they'll take your money to help launch the thing at http://www.kiwisat.org.nz/funding.html; XW-1 from China is going to be fun; SSETI-ESEO will have an S-band linear transponder; Delfi n3xt; the next Indian Hamsat, and *anyone* that wants to cart PE1RAH's little board into space for the relatively minor price of a cubesat launch.
Moreover, in my experience, the majority of 'communicating' -- like it or not -- is done on FM birds, again with a great deal of excellent commercial equipment built for the purpose. Exhibit A: my trusty Arrow Antenna, and SumbandilaSat will give us another target at which to shoot our Arrows :-) in a couple of weeks. http://www.southgatearc.org/news/september2009/sumbandilasat_launch_on_track...
Thats what is intriguing about the SpaceX "launch" campaign...and indeed about the entire changes that are occurring now with the Augustine commission there is a chance for things developing like geo synch "rafts" where very large satellite complexes etc are built. But ham radio will not in my view have a seat at that table unless and until there is some "normalcy" in the mode.
Perhaps more tendentiously, I would finally contend that we amateur satellite folks have indeed created a new normalcy: the steady flow of cubesats and their launches. Until recently, it has been hard for us to capitalize on this situation for two-way communication purposes, but with Delfi C3 and, now, FunCube, I think we're well on our way. As Bob has persistently argued, maybe we should just shoot for 1200 bps and provide a real and workable service through a LEO network.
I spent part of the afternoon talking with a condo owner on Clear Lake about the Club moving its APRS/voice machine to the top of his 14 story building (a virtual skyscraper in this part of Houston)...it was amazing how fast he came around, all he could think of was what went on in Hurricane Ike.
That's great work! Thanks for doing it.
