Subject: Re: Universal tap device



I dont know what macvtap is, but what dont you like about redirecting or 
mirroring packets to tap? Or packet socket?
I think tap has become a christmas tree lately compared to its humble 
beginnings, and its performance is questionable - but it should still
work for what you need.
