Chris -

Yes indeed there is a way to get pids AND corresponding process names. 
I recently copyrighted a program that monitors users activity. It they don't 
do anything for 15 minutes or so, the program logs them out. Part of the
program is a process monitor that gets process ID's and matches them 
against both process owners and process names. 

Unfortunately, I can't divulge any more than this because the company I
work for (Westinghouse) has copyrighted the program and I can't violate
our technology transfer rules.

Needless to say, what you want to do CAN be done ! Just play with the 
calls and read the HP/Apollo "Programming with Domain/OS Calls" manual. 
Many clues lie within. 

Also, don't expect much help from Apollo on some of the stickier issues.
The automatic log-out program I wrote could have been *easily* done better
with a simple mod to the scrto (screen time-out) program, but we could
not get Apollo (Corporate level) to give us the time of day. There is a
wealth of undocumented system calls that perform a *wide* range of
things that could easily do what both you and I want. Apollo *will not*
even discuss the calls. Ask them about "rm" & "idm" calls and see what
happens !
