[TransWarp] Publish/subscribe and PEAK components

[John Landahl]

I'd like to get some pointers on where it might be possible to add  
publish/subscribe features to PEAK components.  I have a client/server 
application where the client periodically asks the server for configuration 
information and work.  Ideally I'd like the information exchange part of the 
client to simply dump the data into the right place in the component 
hierarchy and be able to have other parts of the client receive notifications 
(callbacks would be fine) when the components they care about have been 
changed.

Would it make sense to subclass binding.Component to add subscription methods 
and an overridden __setattr__ function to handle the publications?  Or would 
an entirely different approach be necessary?
