[Mpi-forum] MPI prototype license

I second Alexander's request.

For me GPL is a no-no and my legal department would prevent me from looking at any GPL source code; thus preventing me from reviewing any such code for the MPI forum. The legal department would grant me permission to look at BSD licensed code after consulting with them.

This is regardless of integration to any Microsoft product.

I guess that raises the meta question -- what is the intent?  Is it a  
requirement that the proof-of-concept open source implementations must  
be licensed such that, in practice (not theory) they can be slurped  
into commercial/closed source MPI implementations?  Or is it enough  
that some people implemented it, some [other] people reviewed it, and  
the union of those people have said "yes, this shows what we want it  
to show"?  (and potentially a 3rd set of people who didn't look at the  
proof-of-concept implementation go re-implement it in their MPI  

I thought the intent was to show that the concept was possible and to  
help unearth any "gotchas" in terms of implementation that might not  
be thought of during the design phase.

But to be clear: OMPI, where I have done all my implementation work  
for MPI 2.2 tickets, is BSD (IANAL, and none of this is legal advice  
-- go read our license yourself) so I don't really care too much.
