Cool.

How would you connect OpenBSD to Windows if OpenBSD only supports TUN and
Windows only supports TAP?  If you tried to mix the two, the tunnel definitely
wouldn't work because TAP uses the ethernet protocol while TUN uses
point-to-point IP.

So this means that OpenBSD <-> Windows won't work until OpenBSD gets TAP or
Windows gets TUN.  Perhaps the former has already happened here? :
