[HJ] two questions:
1. this sound interesting, however how to do it securely is the most important 
question, do you already have draft?

2. if the use case is load-balance, then  wouldn't it be better off to make a 
selection right upon client connects (e.g. redirect during IKE_AUTH) than move 
SA around after tunnel is established  ?
