I was wondering about this a while ago and I don't even think you would need to know the IP of partner robots. Your protocol could start off with broadcast messages and each robot could start an election process or something similar to select a master. Unless I am missing the limitations of how the VLANs are setup it sounds like a really interesting case study for students to get some ad-hoc network programming done.

Ideally someone could put out a single API that teams could hook into to establish communications. Then sending could be as simple as calling the API and letting it take care of the networking.
