Jana and I discussed this today at lunch and we think the best approach is for the sender to communicate a value for the max number of retransmittable packets or bytes received before sending an immediate ack.

Number of packets seems simpler, but the resource we're trying not to constrain is CWND, which is in bytes, so that seems more correct.  I suspect either will work fine in typical circumstances.

Given we recommend Reno currently, the default value would probably be 2 packets or 2400 bytes.
