Ok, and then what? Honest question.

Our current plan is to make the source code available and make it free for personal use, but we're not quite ready to open-source it.

Someday we'll probably have paid plans and business / enterprise licenses available as well, but our focus right now is on making it really useful for people.

To me, the whole point of our company is to make these kinds of systems more open, understandable, and modifiable, so at least as long as I'm here, that's what we'll be doing :)

Its not free though. You pay for it by supplying your email address.
