We are working on that at the moment. It won't be as complete as some of the others you mention initially, but it should cover many of the standard use cases.
If you have specific requirements, let us know. If you want to lend a hand, let us know :-)
Is there a target release date?
Furthermore, is there a beta version available?
I would love to contribute but my organization does not allow me any time for contributing to OSS, although I may start to do so on my own free time (which I seem to have so much of, LOL)
Well you should see some capabilities in the MR3 release next week, but most of it will have to wait for the GA.
We'd love to have you help. Just let me know when/if it can happen.
