A clean, lightweight alternative to Python's twisted? http://stackoverflow.com/questions/1824418/a-clean-lightweight-alternative-to-pythons-twisted the new multiprocessing module in 2.6 or I could go for a reactor event based model of some sort. I would rather do the later.. I know about so far Twisted The granddaddy of Python reactor frameworks seems complex and a bit bloated however. Steep learning.. a co routine based solution rather than a traditional reactor callback oriented one. The benefits of this approach are clearer..
