Cool idea. I can definitely see the value of where you're going with it. I like the idea of building integrations and web services on top of this. It's the kind of thing nobody has time to do at their own company, but everybody wants.

Any plans to open source the core? Or at least offer self hosting in some way? Without either of those, it's a non-starter for me and probably a lot of people. Companies are pretty sensitive about their internal architecture, so it might be a requirement for some.
