Well 2500 is much better but the $4500 is still way out of the range of many
hosting companies and developers.
I did see a few other alternitives like Oregano (no real support) and SUSHI
(which I have not used).
The RED5 List however is very active and is supported by the OSFlash
community. So yes there will be lots of support and users. I think they will
have donated several test servers from a number of hosting vendors (one which
is shockwaveserver.com ).
That part is due to launch in several months (fingers crossed). Soooo it is
closer then you think. Real time multi user functionaliy and streaming
technology rolled in to one.
You remember MS SQL Database? They start taking over the Orical database
market then MySQL came out and it is open source. It is very popular now and I
think the a simular path will happen with RED5 Server.
Any way if possible ask some questions at the RED5 forums:

Have a great day!
