Maybe what I do with Z Network Clients is of interest. They act as local 
placeholders for remote Searchable Zope objects (like Z SQL Methods).

- They each have their own URL, although maybe in the future I'll add 
acquisition of a base URL or something.
- They enforce the calling parameters, like Z SQL Methods do. You have to 
declare them beforehand, and the namespace and the REQUEST object are 
searched for them.
- Caching is done the same way as Z SQL Methods, keyed on arguments given.
- You can use traversal and direct traversal on them (again, just like Z 
SQL Methods, http://an.example/Search/id/1234/name/Martijn/displayMethod).

In all respects Z Network Clients sing, dance, and act just like Z SQL 
Methods, except that their data doesn't come from a local DA object, but 
from a remote Searchable Object (you need a Z Network Enabler to make those 
objects available). Apart from Z SQL Methods, you can also query ZCatalog 
objects, ZTables, and Confera topics this way.

Maybe your XML-RPC methods could work the same. If you make them stick to 
the Searchable Object interface, then you can also use them with the Z 
Network objects.. =).
