So I am trying to share access to a custom class object over a network by having a host machine serve it, and multiple clients connect to and update it. It seems that the standard multiprocessing library has managers and proxies for just this usage case.

I believe from reading the multiprocessing docs (and other posts here) that on the host side I need a custom manager derived from the multiprocessing BaseManager class then register my custom class with a custom proxy derived from the multiprocessing BaseProxy class.
