Hi Gary,
What you''re describing is right on track with what we want users to
use Crossbow for. This is a great example of a "network in a box"
scenario that Crossbow is enabling. In your example the kernel pf-
hooks could be used to insert some in-line processing which can add
delays on the datapath. If you need help putting things together let
us know. And if you could give us an update on your progress as well
that would be great :-)
