That would be absolutely fabulous.

Excellent. I'll let Ralph chime in with the relevant technical
details. AFAIK, bproc works just fine in the v1.2 series (they use it
at LANL every day). But note that we changed a *LOT* in ORTE between
v1.2 and v1.3; the BPROC support will likely need to be re-written.
This is likely worth some phone calls to describe what will be needed.
