That would require me to read up on what MPI is and honoustly, I'm not a
big fan on doing that, certainly not after I went to their homepage and
saw around 70 lines of contributing companies, all of them big names.

If my guess is correct, MPI is similar to a CORBA IDL Specification (in
general terms). If this undertsanding is correct then MPI has nothing to
do with the Acrtive Objects as I present them. E.g: the active objects
library cannot perform interprocess communication and certainly not
accross different machines. It only deals with thread activation and
deactivation at appropriate times. To do so, it uses a queue in which a
normal stackframe is pushed and at a later time executed.

People hoping that this is an MPI (in the sense of
http://www.mcs.anl.gov/research/projects/mpi/) for pascal will be
disappointed. Those who are looking for an alternative to thread based
approaches to deal with multiple tasks in a single program might find
this interesting.
