This is related (we have to deal with PPPoE as well), but there are other technologies (VLAN and ATM) that are causing us heartburn at the momment.

This means that you don't Our experience is that not all TCP stacks are listening to MSS. Still other applications (many online games) _depend_ on 1500 byte packets. I think that the MSS hack is cool --- it would definately address the small drop in efficiency that frag-anyways would create, but I still believe the frag-anyways to be necessary due to the number of broken protocols out there.
