My thought on the subject was that dbus may not be well suited for network communication because it's a binary protocol. The problem comes in when the application on the other side of the tube does not speak native dbus(php or java apps). I think xmlrpc may be a good alternative in this case because it is very simple, and its an established rpc standard on the web. Its also a XMPP standard(XEP 0009). There are several ways you could introduce this without breaking everything in the process, for instance, a new tube type could be created to support xmlrpc, like there is for dbus. That way, applications could choose to use the rpc mechanism that made sense for that app.

I think XML-RPC could be useful, but I'm worried that its usefulness would be
limited.

As I understand it, XML-RPC is more or less a client-server protocol, whereas
D-Bus gives us quite useful semantics for group communication. It's true that
D-Bus is not as widespread as things stand, and sending binary messages over
XML has always felt a bit nasty. I doubt our protocol will get standardised in
its current form, but I also think that XML-RPC is a less useful model for
writing collaborative applications.

We should certainly consider all our options though.
