There are some early components available, see
http://git.denx.de/?p=xenomai-solo.git and
http://git.xenomai.org/?p=rtdm-native.git.

Yes, the plan is to allow easy code migration between both RT models,
and that would include code written for the Native skin.

I had some chat with the guy who is working on RTAI for m68k, which
included writing some I-pipe-like patch. Unfortunately there was not
much drive visible to push that part upstream. But it's released now, so
someone else could pick that task up.

E.g. RTLWS [1]. At least /me plans to attend (though on a non-Xenomai
topic).
