I've added chuck to the this CC: list. Also just added jason, I'm hoping 
that the fact that we're mixing Jets and Sharks is not a problem :-)

I still like IF per VC. Thus I am hoping to see IF per VC added to chuck's
code or to the system itself in some way. Jason Thorpe of netbsd has some
good ideas in this area. I have looked at chuck's code quite a bit and feel
that it is not incompatible with IF per VC.

I'm interested. 

The card I'm building is going to require that a virtual interface per vc 
work in some way. 

thanks julian, this is really interesting!
