Hello,

I wonder if it's possible to use the RT pipe to exchange messages 
between two real-time task (in primary mode). The existence of the 
undocumented function rt_pipe_bind() makes me think so.

Nope, this won't work with the current implementation. A message pipe always
connects a real-time endpoint with a regular chardev endpoint.

We could enable this feature in 2.5, but now, we have buffer objects available
as well in the trunk/, which would make this redundant.
