It's just like on lan... internet is almost identical to lan, so our messenger would work, just remember that for some situations you would need external server with public IP to be able to connect with all peers. It also depends on style of messenger, eg p2p p2s2p or something.

And, be sure the messenger port is open on the (Windows) firewall.

--No one's perfect, answer edited for first one being quite one track minded--

So, to use proxy... you'll have to get running proxy server that is open on your port or you'll have to get proxy info (hints @ http://www.scalabium.com/faq/dct0161.htm ), then propably check for code or wait for someone who has patience to get the proxy code for you or give sampe or smth, then incorporate your protocol in it and viola, you're done.
