cddb client protocol implementation

[teratorn]

I had a quick read through your code and it looks pretty good. The doc strings
are refreshingly well done :)
One question I have right now,
Have you considered writing a client interface that uses deferreds?
I understand that this is just a protocol implementation, but to
be most useful, users are going to want to integrate with their
existing deferred-using code.
I suggest you rename the CDDBPClient to the more verbose name
CDDBClientProtocol. Then provide a high-level CDDBClient which one would use to
connect to a cddb server and run queries. Appropriate methods should return
deferrds, and the implementation would gather the results as they are available
and fire the deferred once a full response has been received.
What do you think?
Anyway, it's late and I'm heading to bed.. maybe I'll think of something else
tomorrow :)
