For simplifications I'd prefer the "sticky" way too, though, it should be possible to broadcast the session to other tomcat instances too. That way, JSF should work in such environments too. I've never tried it myself, though.
Don't know much about the network load you might experience when you have to synchronize the session after each request. There are ways to synchronize changed session attributes only, but this might not work with data structures we use in myfaces, however, even if any clever thingy builds the session delta, at least the whole session has to be serialized locally.
