Public looking glass are for humans.
I do not want my looking-glass being heavily loaded by cron tool.

looking-glass use router CPU and i do not want to see a foolish guy to
put a :

Crontab  ...

Route-server is a solution to have load CPU router.

This raises a good point. Since most LGs are running on a dedicated web
server somewhere inside of a network, one could very easily install zebra on
this webserver with a read-only BGP image from several internal routers [say
all the borders]. This has two benefits: a) Queries do not bog down
production routers in fact the load is linear, and b) The LG tool only need
look at localhost for all answers. This only costs 120mb of RAM per view and
saves network overhead to boot.

Traceroutes may need to still go out to the end router, but I doubt anyone
would allow a query to those in an automated fashion.
