Yeah, this is a really cool problem Space. I’m working on something similar. I think the interesting thing of like truly connecting two points on the Internet, which almost seems something the Internet was designed for, but we can’t do it because of NAT is really worthwhile and interesting.

I’m super attracted to how to do this without creating some kind of overlay network. For instance, tor is extremely robust at connecting through NAT but it’s essentially because of outbound connections to a global overlay network.
