I'm not sure this was the main goal of annex E, perhaps an Ada
"historian" can confirm. Annex B (Interface to Other Languages) seems
more relevant for this topic.

PolyORB *c*ould, the "only" point is to provide the corresponding
protocol personality (if MPI defines its own protocol), and (I
suppose) some way to map Ada calls onto MPI functions (and
vice-versa). I'm not an MPI expert.

There already exist mappings for CORBA <=> DSA (quite natural in most
cases, ses Quinot's paper on CIAO), CORBA/MOM (requires some
thinking), so why not for DSA/MPI.

*sh*ould is another question .. but we welcome all new contributors
onboard ;)
