Hi,

That would work if our app was less complex, too much work involved..

We've developed on it the last 8 years and have used the session scope since it 
was possible.

We use sticky sessions and also cookie based persistence in the load balancer 
(Coyote) and it's pretty stable, users is seldom balanced over to the other 
servers - but session replication would make it even more stable.

The other clustering approach is to use Client scope rather than Session scope. 
 To overly simplify things, Client scope is a contract between the user's 
browser and the application, whereas Session scope is a contract between the 
user's browser and the server.  Since Client scope can maintain state with the 
application, a user can be seamlessly bounced from server to server without 
loss of data / connection.  Works really well behind hardware load balancing, 
for example.  Not so sure it fits your situation, but thought I'd at least 
mention it in case.

Just remember to never, ever use Registry as your Client scope store.  It's the 
CF default, but it can quickly overwhelm server swapspace.  Go ahead and use a 
datasource instead.
