I'm wondering if anyone has seen an application that does the following. I'm looking for a peer to peer type chat program that runs on OS X and windows. I don't want to have to sign up with MSN or Yahoo and login to one of their servers. I just want to be able to install some software on my computer, and on my wifes computer, that will allow us to send bits of info, like URL's, back and forth in realtime. Has anyone seen software like that out there? Thanks, Spencer.
