Wasabi has a port of Netgraph in its modified NetBSD tree.  However, 
not all of the modules have been tested, and I also don't think that 
it's really the right direction to go.  I'd rather that the entire 
network stack be made generic enough to provide Netgraph-like 
functionality without having to use a bolt-on.  (Netgraph's integration 
is... not very clean, even in FreeBSD...)
