If you read what I wrote (possibly reading between the lines a bit), you will 
see that I suggested to keep something like 10 to 100 buffers in memory 
between the ACKs.  100 such buffers would probably amount to less than 1MB of 
main memory. This could be something that the user configures as well.

That might be possible, but would be a lot more work, IMO.
