I'm still using it, and I have no regrets.  At this point it's processed
literally hundreds of hours of jobs over a 3 yr period, with ~5-10
machines on the processing back-end.

My one caveat is that managing multiple processes on multiple machines
can be ... challenging.  For example, I still have no automated failure
recovery: if a process dies while executing a long-running task, there's
no easy way to tell short of watching for jobs that fail to execute in a
reasonable time frame.  This situation is rare, so I've opted to involve
a human (by automated e-mail notification) rather than have some more
complicated watchdog process system set up.
