(IBMer working on said JIT here)

As Chris Seaton points out as well, we're not really open source yet. Working on getting there, but it's going to take time. The important thing now is that we can start talking with the community and making it more likely that when we do get open source, it can happen in a way consumable by the Ruby community.

I can tell you that I tried your fork on some toy projects and.. nothing really to report, other than, I'm really scared something this good won't go anywhere.

Fingers crossed to seeing this hit mainline soon.

do you have any status of the project? Or any dates when we can expect?

Unfortunately no dates. We're still working on this, but we really want to do it right, so we're taking the time we need. Sorry!

I don't think that will happen for a while, if it does happen. They haven't even released their patch under a compatible licence yet, or their library as open source, for example.

Thanks for reposting this. Wonder why it's not making bigger waves. What are the performance numbers of this thing like? I feel this IBM OMR is a reply to MS opening .Net CLR
