I'll forward the suggestion to Javier. I'm personally not competent to 
try to make a patch. The MPITB code is GPL'd, though. The source code 
all lives in a single directory. It compiles to a bunch of .oct files 
that are bindings to the LAM-MPI functions. I think someone with 
reasonably good knowledge of C and Octave's internals would have 
little trouble with the job.
