In PSHB, you subscribe to a stream of data that is published to a particular "topic" or within a named feed. It appears that what you're asking for is, in part, for PSHB to be extended to also support "content-based" PubSub -- or, the ability to subscribe to filtered streams of data where the filtering is performed on the content of the message, not merely on the name of the topic to which the data was published. Given that PSHB is already topic-based, my assumption is that you would want content-based filtering within streams of data which would correspond to the existing Topics. Thus, you're asking for a hybrid system that implements content-based filtering over topics. I recently wrote a note proposing precisely this. Take a look the following and consider providing your thoughts: http://groups.google.com/group/pubsubhubbub/browse_thread/thread/2fdbd65bbb8602c8#
