Yo Miroslav!

I'll wait to respond after 3.11 ships (today?).  I think
we are pretty close, but since a 3.12 is on the road map soon I'd
rather observe the pre-release quiet period.

I had always thought the time server howto was for local, not
public access.  If it needs to cover public access then the
ntpd side also needs more work.
