Yes, pvm_psend/precv completely bypass the XDR layer for purposes
of speed. This is a feature not a bug...8-) If you're communicating
between machines that don't share a data format, the message
packing phase won't be your bottleneck, the data translation
phase will be. 

If you actually look at the source, you'll see that psend()
does a initsend(), pack() and send() underneath anyhow...

Just out of curiousity, what machines are you on? I'll
put them on my list of "machines to never buy". Everyone
say "IEEE" is a good thing...
