It seems this will slow things down a LOT, and considering MPI is usually used for
high-performance computing, I wouldn't make this standard behavior.
You might look into making it work with kerberos4kth's krsh/krshd for strong
authentication
without the encryption overhead. Unless you really need all communication to be
encrypted
(doing classified computations on an untrusted network? :-).
There's also heimdal's rsh/rshd.

I'm pretty sure your best guess is right.
