there's a difference between the ability to deal with high bandwidth and
security.  a packet that's dropped because the interface is too busy
is the same as a packet that's dropped because of a filter- it's
dropped in either case.  if you know differently please share
your information with the list, as i'm sure that the rest of us will
find the information important.

an observation:  posting criticism of other vendor's products while
providing no numbers or details, then offering your services is not a 
good way to convince your readers of the validity of your opinion.
