Is there a Flash Media Server Developer Edition for the Mac OSX ?I saw a Linux
version, but don't know if that will work for me. I am trying to develop an
application on my Mac, but would actually use a Linux server.

I can't say I've ever heard of anyone successfully installing on a Mac.
Something tells me it's not going to happen.

I've read of people installing on just about every flavor of Linux, and ince
it's just a development machine you could get a $100 pawnshop special and load
it up with a free build of Linux (or windows XP if you have a copy). I have an
old 600mhz celeron machine I've used as an FCS dev server in the past, and it
worked just fine.
