IDS test tools and cool gigether device.

Hey Peter,
   Cool.  I was wondering when someone was going
to actually do this.   Because there has been a void
here, I've been thinking about how to do this with
simple commercial gig-ether switches, and, of course,
the ubiquitous BFR (big fxxxxxx router). It may not
be that hard of a problem after all.
