external process driving perfly

This is probably not a direct Performer question, though I am sure many
people must have tried this. I have written a simple perfly-like app,
where I update the XYZHPR coordinated via mouse (Xformer). I would like
now to control these coordinates from an external process. What I would
like to do would be to have my app startup, allocate a global structure
containing the 'pfCoord view;' and then somehow startup another process
(called, say, 'driver'), and communicate to it the address fo that
structure, so 'driver' can write values to view, to be read at every frame
by my flying app... you get the idea.
Are there preferred mechanism to do this within Performer? If not, what is
the simplest call that will make this happen? Something like sproc() or
maybe system()?
Any help would be appreciated!
Thanks a lot,
Carlo.
