RE: OScheduler

James was offered to join OpenSymphony and the offer was never
retracted. Quartz is a great product and we'd be lucky to have him
contribute to OpenSymphony as a whole by adding another great product.
As for your three questions, I don't see how the third one really
matters. Re: the package name... yes, we'd like for it to be
com.opensymphony.quartz, though that could happen later (like during a
major release) as to not upset a current release branch (1.x, for
example). 

With regards to the simplicity, I've used (and dug deep in to the code)
Quartz pretty extensively, and I would be happy to see it with OS.  We
have projects ranging from simple (OSCore, SiteMesh, OSCache) to much
more complex (OSWorkflow, WebWork, OSUser). I think Quartz would fit on
the more complex side of the curve, but that's OK.

The only thing I'd like to see with Quartz in the future is pluggable
persistence (in the style of OSWorkflow -- it seems to be a pretty
popular "feature"). 

Anyway, James, I think if you joined up with OpenSymphony you'd be very
welcome. Mathias, Hani, and I would probably be very eager to help you
out wherever possible. And I'm sure Mathias' scheduler has a lot of good
ideas you can integrate in with 2.0.

I'm still waiting for an answer of James.
