[MPICH] Porting the MPICH "back-end"

[William Gropp]

Hi,
In addition to some of the documentation that is available (and the  
information on the web site), we'd be happy to talk to you about the  
current state, answer questions that you may have about the design,  
and even entertain changes that might make your project easier.
