You are correct. In previous version, only object which supported the serialization method like strings and query objects would replicate to the other instances in the cluster. CFC's and XML documents (which Ben said are stored in the same way) would not serialize and therefore would replicate as an empty object with a "serialization error" name. Very annoying indeed.
CF 8 plans to properly serialize CFC's so they can be replicated to the other instances in your cluster. If you don't use sticky sessions, or if an instance goes down, the JRUN connector Round Robins the user over to the next instance in line and they never even know the difference.

Now, someone correct me if I'm wrong, but the issue everyone is speaking about is: simple variables would replicate, but objects would not replicate (user beans, cfc's with cart info, etc), and they will replicate in Scorpio.
