Parsing Server-side

Parsing commands server-side may run into a few issues, the first of which is that returning an object over XML-RPC does not work the way that I imagined it would.  While it provides the objects' members as a dictionary, it does not provide any information about the instance of the object -- for example, whether it is an sbInitCmd object or a sbClickCmd object.

I can make a work-around for this (for example, by making the class name a member, and then passing that to another function that re-instantiates the object) but it seems like a giant kludge.
