Sorry, pb is Perspective Broker, a protocol for the twisted framework. 
One can create clients and servers using an efficient serialization of 
objects over the wire. The main thing is that it provides access to 
objects on either side of the communication to make it fairly easy to 
execute methods on them. Just another rpc but with a safer object 
serialization than a pickle and more efficient than xmlrpc (or something 
as ridiculous as soap).

Ok sure, not a problem. I realize PyLucene wraps lucene but between the 
two I do not know besides remote api, whether there is any other 
functionality that has not been wrapped. I'll see what more I can find 
on the lucene list to try and educate myself a bit more. Many thanks.
