Now that IronPython2 is out, wondering about IronPython on Mono...

Any idea what version of Mono that is? Does IP2 build with Mono 2.2? It
would be great to put out a IPCE r8 for IP2.

Also, what would be the matching versions of IronRuby that would work with
IP on Mono? I see that DevHawk has a DLR nightly build that comes with Ruby
and Python:


but the early builds seem to be empty (I've sent Harry a note about that).
The latest versions of those builds don't quite work with Mono 2.0, but
perhaps Mono 2.2?

Thanks for any assistance!
