Field replication for session data

We should have an AOP-ized fine grained session replication system. Meaning if I stick a pojo into the session it should optionally break apart to its state and replicate accross the cluster through the deep object graph. Same deal for SFSBs.

Thus

Customer cust = new Customer();
cust.setName("George W. Bush");
cust.setAddress("123 Don't call it Waco TX");
cust.setCity("Craford");
cust.setState("TX");

session.setAttribute("customer",cust);

cust.setAddress("1600 PA Ave");
cust.setCity("Washington");
cust.setState("DC");

should only replicate address/city/state and not serialize the whole object – I should not have to call set Attribute(). Furthermore if Address had been a setter on customer and I only changed "street" then only street would replicate.

Lastly, it should be optional to transactionalize these for the scope of the replication (meaning I could say I really do want these transactional so that I send one message and not 3).
