Since both of these are already relying on a pull mechanism at the initiation of a transaction, it isn't clear to me how they would be significantly more adversely affected by using a pull-based mapping mechanism. > 3) Server responds to a simple client request via an asymmetric path. > No DNS occurs here, and the response goes via a router not involved > in the client-to-server direction.

I was wondering if you had concrete examples of existing applications that would fail with an increase in initial packet latency.
