I think that Calm is stressed out by this kind of thing - he's only 20. I don't think he likes the deadline pressure and the pressure of having to deal with new features that will never end, fixing bugs and irritated webmasters who want things fixed yesterday, then all the support he'll be responsible for when the product is sold publically - just wants to wash his hands of it. He likes to work on open source stuff - at his own pace. Let him bow out gracefully. He's given you the code free after all that work he put in.
I don't think he's a flake - I think he's 20
We all talk in this biz about the young models being so hard to work with and frustrating, it's not just because they're girls and not just because they're girls who take off their clothes for money - it's being 20.
Konrad told me he was great with AJAX so I was planning on hitting him up some time for some stuff.
