  | 1) If you only create a RoundRobin version of this, and people configure it for an SFSB, a client that doesn't start a tx can't get sticky session semantics (FirstAvailable).  Even if they do start w/ a tx, they become unstuck if they keep using the bean after they commit the tx.

Yeah, you're right on this. So, I believe you suggest that I create different versions of TxLoadBalancePolicy which default on the ones mentioned above (as well as RR) if no transactions are running, correct?
