Indeed!  Regardless of how it's actually implemented under the hood, I
agree this idea of having "virtual" interfaces for each "endpoint" in a
VPN environment is a very good model.  It solves the same kind of
problem in the same kind of way for every tool that already deals with
these issues by identifying a specific interface, including IP Filter,
BPF, and maybe even routing and bridging.
