My friend who started
Meetro might be interested in selling. They have created their own custom IM and IM network, with full social networking features (profiles, messaging, feeds, friends) and have location oriented IP & Wifi technology that helps geolocate users. If you're unfamailar with their product, you should definately check it out. Maybe you don't have the money to buy the company, but it is fucking cool and worth checking out.
If you are interested in getting into mainstream and have some serious capital to do so, let me know and I can put you in touch with my buddy.
