vkernel and testing IP Filter

["Jeremy C. Reed" <reed@xxxxxxxxxxxxx>]

I am hoping I can use vkernel on leaf or pkgbox to do some IP Filter 
coding.

Can a vkernel be used to test packet filtering, networking and tcpdump?

Or maybe as an alternative, I could do my testing within bochs or gxemul 
environment and use kernel module(s) -- so I don't have to continually 
reboot my system for testing.
