who offers cheap (personal) 1U colo?

Restrict it to people you've met or spoken to enough
to think you know them..

That is the problem. Password access to a members-only
looking glass can prevent temptation and grief. And
nobody needs shell access per se because we are talking
about people who have root on their own servers.

Some people have done a lot of work on locking down
the original looking-glass script. Is there a version
of this that is generally accepted to be the best?

How useful would it be to folks to have access to
a set of looking glasses that have a few more options
than the classic one, i.e. TCP traceroute, PathChirp
one-way latency measurements, etc.?
