threadedselectreactor (in svn, will be in 2.1) runs the blocking part  
of the reactor in a separate thread, so you could do blocking PB- 
based RPC with that..

I just checked in an example of how you might be able to use it:
Twisted/trunk/doc/core/examples/threadedselect/blockingdemo.py

Not really tested or thought out very well, but it should work.
