Well, what I (personally) want to achieve with Orocos is that this kind
of design will not be happening anymore after Orocos has matured :-)
Why? Because starting a design with saying that you need fifo's to do a
job is mixing up things, and is the reason for non-portability of
applications.
Anyway, if you want to define fifo's and threads yourself, you'd better
not try to use Orocos, because it will create overhead for you. And the
transparent IPC is exactly a part of Orocos that is not yet
implemented... We are working on the _infrastructure_ and not yet on
applications.

But of course, this doesn't help you at this moment :-(
And I have no real advice at this moment, because I know that things are
still changing before we reach 1.0...
