WSDL V2.0 adds HTTP verbs to the specification and *could* be used to describe a REST service, although I think WSDL is still far too verbose for what we need.
There's also WADL (developed at Sun), which is much easier to write than WSDL.
Personally, I think we would get more traction with developers if we focus as much attention on REST as any other definition.
I think there are at least 3 reasons I can see to focus on a REST/JSON approach:
1. Seems to work for Google, but more to the point, some cloud print implementations may have a "connector" or interface to Google Cloud Print, which is REST/JSON based
2. There are other APIs that are primarily REST-based that will probably be needed by cloud print modules, such as OpenID and OAUTH 2, and these implementations can just make use of the same RPC facilities
3. It's easier to implement REST than SOAP, and we don't need all the SOAP baggage to realize our services.
