What is LVS?

Many applications are already converted, but are often pre-compiled without
such support. If you compile what you use from source, that's not a
problem.

That will eventually change. Tunnels aren't so difficult. I've used them
for 3+ years.

Advantage: No port scanning as the address space is really too big for such
to be practical. My firewall throws away about 30MB of packets per week of
port scans and other intrusion attempts to services I don't run.

However, also this week, there was a single attempt to spam over IPv6 (it
was "successful" for the spammer, but he spammed a spamtrap). Maybe it's
time to start an IPv6 based DNSBL?
