If we want to increase deployment rate, it should be easier in the
residential or enterprise firewall (e.g. rolling it into OpenWRT or pfSense).
Not sure whether NAT is still prevalent in IPv6 deployments --
if it's running as an IPv6 router/firewall instead of NAT 
you'll probably have to handle OE at host level? That would pretty
much kill it.

Is this the BTNS approach, or do you need PKI or DNS access for it to works?
IPv4 or IPv6, or both?

I'm reasonably sure that there is a potentially huge demand for 
passive attack protection for end users and enterprises. If this
could be package-ready for Linux or FreeBSD then eventual deployment
numbers could be considerable.
