Re: Small hardware network sniffer - does it exist?

["Matthew Leeds" <mleeds () theleeds net>]

Try searching on Single Board Computer or Embedded System. You'll get stuff like this:

It just takes a little filtering to find dual Ethernet devices. You could slap a small LCD display on this, even a 
touchscreen for basic interfacing.
