Some providers are VERY paranoid about people seeing what their routing
table looks like.  I requested that one of our upstreams provide a
looking-glass and their reply was "The LG code requires that we open up
RSH on the routers.  No Way!"


I wrote looking-glass code that uses telnet.  I provided it to the
provider in question.  Still no looking-glass nearly a year later.

Oh well.
