James: Are you aware of a Windows tun project? While most windows users may prefer tap, I am interested in the point-to-point nature of the tun device. When setting up many routed connections, it seems that each TAP connection will use 1 ip and waste 2 others. I can also live without broadcast traffic and non-IP protocols.
_SNIP_ I think that Windows users are going to prefer a tap interface anyways, because it carries the kind of traffic and protocols which Windows applications generate, such as broadcast traffic and non-IP protocols. James
