To clarify things a bit, I hope.

In the beginning was PBS - developed in house at NASA by engineers
who needed a Portable Batch System.  If you understand Cray NQS syntax 
and concepts it's familiar :) They left / sold to Veridian who in turn 
sold to Altair.  The original PBS was GPL or a close equivalent, if I 
understand correctly.

Altair are marketing a propietary development of PBS as PBSPro.  OpenPBS
remains available, though you have to register with Altair for download.
What they have done very recently, which is rather sneaky, is for the 
site to oblige you to register for an evaluation copy of PBSPro and 
potentially answer a questionnaire prior to providing the link to allow 
you to download OpenPBS.

OpenPBS is not under active development and PBSPro may have stalled.  
Certainly the price per node that Altair are quoting has apparently 
dropped significantly - though their salesmen are still persistent :)

The academic community and the active users forked OpenPBS to create 
Scalable PBS [SPBS] which is the name most widely known.  They've added
patches, fixes and features, though there is still an Altair licence for 
OpenPBS in there.  In the last couple of months, SPBS changed its name
initially to StORM and then to Torque.

HTH other relative newbies who may be confused by trying to find the 
product :)
