Well it's an extension and we can't depend on it being installed on
most servers. That and the warning on the PHP site says it all: "This
extension is EXPERIMENTAL. The behaviour of this extension --
including the names of its functions and anything else documented
about this extension -- may change without notice in a future release
of PHP. Use this extension at your own risk."

Yes, it's just a function call.

I've done a bit with XML RPC in the station module. The archive and
schedule sub-modules are desinged to run on different machines and
grab program information remotely. The code is sort of scattered
around but it's a working example.
