   resend joystick input to other PCs
  Is there any existent application that resends joystick input to any number of PCs? (server-client model, through udp broadcast or similar)I'm thinking about writing this but in case it exists, please let me know so I can save a few hours.I think some utilities for gaming should already allow this, I've seen people play WoW with many PCs at the same time, but I don't really know where to look at...Thanks!
