Myrinet is coming very rapidly, and I think myrinet should be considered.
Well, that's my personal impression. (We have a cluster with 
myrinet here).

And I think mpich has less requirements before setting up (requires only rsh).

Just some counter-proposals which come up to my mind.

I guess you should use the 
DEB_BUILD_OPTIONS=mpich 

thing.



I would probably like to have both versions in Debian anyway, 
but that is my opinion...
