I don't think so.

It depends as always ;-) what your application glues to the

"Session replication is crap because you don't really know what is 
happening when it does bad. It is crap also because you spent a lot of 
money to maintain and control it, get increased complexity which tends 
to fail earlier and this just for a 0.5% increase of availability for 
your users (not the system per se as with sticky sessions you gain the 
same system availability rates).
