Me too asked Gregory for some discussion on this long ago but received
no response.

Anyway, the critical thing beyond latencies remains *maintenance*. If
someone decides to apply I-pipe on RTAI *and* doesn't forget to
contribute to the mandatory bits of the Adeos project, work actively
within that community (test new versions and report results, track down
bugs, port to new kernels releases, etc.), anyone would benefit in the
end. BTW, that would surely stimulate discussions about differing
numbers on both sides as well.
