When I did the networking for Run-A-War last year I first tried to do it with the Indy components (UDP if IRC) - however the Indy components used all the processing power on the PC monitoring the Ports that my game didn;t work.

Thanks to Technomage I got the networking working with SDL_Net.

I would love to see something like this getting off the ground but I agree with WILL it should be free for use in the same way SDL is available to everyone.

Where possible I'd like to help.
