Chat for programmers?

when sharing applications with collaborators it would be more than awesome to be able to have some sort of chat on the the rare wire website so that we (whoever is a collaborator on that specific app) can actively discuss code while viewing the code. It would allow groups to work from various locations and collaborate more effectively than just sharing an app with someone and either calling and discussing certain points. It may not be what the website was initially intended to do, BUT it would add a lot more value to the user experience. It would make development for projects much easier.
