This is how flash proxy works. Clients register themselves as needing a
connection, and then proxies connect to the clients. (The problem is
that many *clients* are also behind NAT, and then it doesn't work so
well.)

You can run a flash proxy just by going to a web page like
http://crypto.stanford.edu/flashproxy/, and there is also code to run a
proxy in the background without a browser:
