   Yes, frame sizes have been addressed, but last I checked, everyone 
was implementing jumbo frames differently (and incompatibly).

   That's a very good question.  I understand GigE is much better than 
previous Ethernet standards (beyond just the bit clock) but I don't 
know many of the details.

   I have two HIPPI switches.  I paid $50 for one and $100 for the 
other.  I believe Brian (up near you) has at least three of them 
(though physically very large ones) that aren't doing anything.  But 
otherwise I agree with your points.
