All shmem communication is handled by Nemesis directly. Actually, the MX 
module disables the Shmem support available
in the MX layer.

Oh yes. I see.  AFAIK, there is no support for multiple networks (and 
thus modules) at the same time in Nemesis.
when you select a module/protocol, you have to stick with it. But maybe 
something could be done with Open-MX?
