I would love to know more about the internal workings of WinPcap to see if my concerns are well-founded.  I am early enough in development that I have not yet tested how much latency each component introduces -- I just wanted to be aware of any potential problems before investing a lot of time in development.

I can tell you that at moderate traffic loads (2Mbps bi-directional), I get about 1ms delay
when bridging a packet through a system using winpcap as the packet receiver logic.
