...Over the web...

I mean, Git and Linux are developed via email lists, which is a decentralized way of sending pull/merge requests, isn't it? I guess you could argue the mailing list is hosted on a server, fine. So then fine, usenet.

Yeah, email and nntp are old crufty technologies and there are obviously advantages to having a web based interface and a central place to go for a project. But git itself certainly supports a decentralized mechanism for merging.

So then the question really is, how do you decentralize a web interface, isn't it? The dvcs itself isn't the problem.
