wow!  quite a list of recommendations...  a few comments:

-- about those "incredible" forwarding/filtering rates.  
   many of them are BUNK!  there is no good standard for measuring
   bridge performance now.  the chair you are sitting in could currently
   be said to have a filtering rate of 1 Gigapacket per second.  

   forwarding rates can be misleading as well.  what happens when
   your destination ethernet is busy?  are packets dropped?  
   buffering and load-smoothing characteristics are important and
   can be largely independent of filtering/forwarding rates...

-- the DEC bridge had a bug -- but it is still the standard by 
   which bridges are measured, with regard to performance.  it's quick.
