ok, well here is what is happening as I know it
rfisher(C2) is working on a PhoneGap plugin. I've heard it's in the works and coming along, but nothing ready for release.
JameS327(Ouya dev forums) is also working on a PhoneGap controller plugin. It's also coming along, but no word as to what sate it's in. I've suggested that they pool there effort and resources. No word on that either.
As for CJS. The problem isn't performance. It's that CJS crashes on the Ouya. With that there doesn't seem to be any reason to push CJS further until new news comes. I've asked Ludie on the forums, and while interested they haven't shown any enthusiasm to have it ready by early April :( I've asked the Ouya team to see if they can nudge them, and mentioned they would, but I haven't heard anything as of yet.
As for PhoneGap. We are waiting on the news from Lorenbeer? who is working on a plugin for PhoneGap called Pender. Pender design is to give PhoneGap an accelerated Canvas. So with rfisher and hopefully Pender ready by late March we might have a build profile for C2 to the Ouya.
As for myself. I've been tinkering with GameClosure, but am having problems with getting the right Canvas for C2 to use on an android device. Also the GameClosure support is seriously lacking. GC has a 9 man team where as Scirra with it's 3 man team replies 30 times the amount.
As for Scirra. I haven't heard anything from Scirra in regards to working with the Ouya. Honestly I think that for except a small internet niche most don't really have any interest in the Ouya. It's no IOS or standard Android so most are sorta meh :(
I feel however I'm sure we will have something cobbled together by early April :)
