Agreed. The only thing that I have some concern about is the reinventing of the wheel in python. multiprocessing Managers are one viable option that’s existed since python 2.6; there’s a learning curve though, and you’ll run into problems with pickling some objects because the pickle protocol is far from complete (example: http://stackoverflow.com/questions/1816958/cant-pickle-type-instancemethod-when-using-pythons-multiprocessing-pool-ma ); you might run into this problems regardless because you’re serializing objects using pickle instead of using dill (or using a simpler serialization method like JSON). Fabric has a framework that’s nice to use if you have ssh capability. There are other frameworks that use twisted conch I think too (another library that implements ssh access). Isilon has a framework they use, but it’s very customized to their infrastructure and product assumptions and it’s in need of an overhaul :(. -Garrett
