I would prefer not to encrypt the Retry packet and keep things how they are. We've done a lot of work to create a design that requires the least amount of work to accomplish the stateless retry scenario. Adding an additional level of encryption, just to get a checksum (something that is practically, already accomplished in most deployments with UDP) is just going to add complexity (we've already started work with HW vendors on the current model, and it's complexity, compared to TCP, is already a major hurdle).
