Maybe you could set up the SSA Convention Video CD (it actually could be just a download to reduce cost) like Greg does the tee shirts (sort of the Kick Starter/Groupon model). Have people pay (or commit) and only when it hits the critical mass does it happen.

Then you only put effort in if you have cash. The other question is whether the video cannibalizes the convention attendance - but only a real life trial can tell that.
