That's one solution that I had considered, but in this particular case, I will probably use the CGI version of the XMLRPCServer since I can get the information from the REMOTE_ADDR environment variable that apache will set for me. The problem I'm working on now is to have our client's machines connect to our XML-RPC server in cron jobs which will do at least two things, check to see if their dynamic IP address has changed so we can update DNS for them, and/or let our system know they're still alive and functioning. This part of the job is probably best handled behind apache using the CGIXMLRPCRequestHandler as it makes some things simpler and can be done via https. Being fairly new to python, I wanted to know if there was a clean way to get parent information if the author of a package hadn't provided this. I generally have attributes in children that point back to the parent making it easy to get back to the parent from the child.
