The multiprocessing module, new in the 2.6 standard library and 
available in PyPi as a backport to 2.4 and 2.5, supports managing of 
processes on both local and remote machines.  The 2.6 module 
documentation has an "example/demo of how to use the 
managers.SyncManager, Process and others to build a system which can 
distribute processes and work via a distributed queue to a 'cluster' of 
machines on a network, accessible via SSH".
