It's not often that I actually release code into the wild, so I figured I'd drop a pointer to an early beta of a project that we'll be using on lefora, our free forum hosting service.
From jobba.TheHutt's google code project page:
A simple, reliable, high availability, distributed job queue/worker system, written in Python.
Author's note: the project was largely based on bradfitz's project, TheSchwartz, hence the questionable taste in nomenclature :)
