Can't tell from here what's "going over the wire" with your code, but as 
long as the error message has the word "mutable" in it I wouldn't expect 
trouble with the parameters as such, more with the references.

Is there a particular reason why you can't/don't want to use ZSI? It's 
what e.g. vboxshell.py uses if one selects the webservice. It gives a 
nice, direct python object interface to the API, and can also talk to 
the local API when it runs on the same system...
