I never saw the code, sorry.  I wrote hogwash about a year and a half
ago.  I just wanted a toy that worked.  If we're duplicating labor, I'd
love to merge the two if the code bases are compatible.  More developers
make a better tool.

One differences between the two, is that hogwash will run without IP
support compiled into the kernel.  That was one of the constraints I was
working under, but I agree with you.  We should make a tool where people
can choose thier injection mechanisms.  There are specific things for
each OS that can accelerate it.  I think we also need a very portable
version.  Netfilter doesn't work well on thing like AIX and on embedable
OS's that aren't based on unix.
