Hmmm....

Two things I suppose:

        * I didn't realise it was "that recently" that MTU discovery
          came in - OOI do you remember when this was?

        * I hate a load of things about TCP/IP and one of them has to
          be the way these things are kludged together - there are
          much better ways to do packet size calculations than trial
          and error :P *cough*ATM*cough*[0]
