(Your emails are html and very hard to read.  Please use plain text
only in the future.)

You will have mpich2 problems as well, if you expect users to use IB
or TCP or GM for message passing in their clusters.  This is a hard
problem for all software vendors.  Shipping source is your best bet.

Failing that, shipping binaries that expect certain mpich2 and pvfs2
shared libraries may work.  We can't help you with much of this, but
if you identify a specific problem in pvfs2 that keeps it from
working for your multi-device setup, let us know and we'll see if
it's fixable.
