Question

Are there any open source cross platform NAT punch throughs?

Answer 1

I haven't got an answer here I'm afraid, but I do know that a couple of years ago there was some research done in area that ended up spawning some IETF documents. The curious reader might already be familiar with these:

• http://tools.ietf.org/html/draft-ietf-behave-rfc3489bis-18
• http://tools.ietf.org/html/draft-ietf-behave-turn-13
• possibly http://tools.ietf.org/html/draft-ietf-mmusic-ice-19
• (...your-link-here: some research that I probably have missed)
