I haven't use linux in a while partly because I always end up needing to use some program that is windows only. I'd like to hear from those out there that use linux and hack this game. Any limitations?
As far as tools, RABCDAsm is the biggest tool for modifying .swfs and can be compiled under linux. Also if you're looking to do a proxy, there is nothing really stopping you. Just pick up the proxy source botmaker posted a little while ago and get yourself an ide like eclipse and start poking around.
