remote monitoring plugin? (but not a gateway)

[tswalker]

I'm interested in adding a few (one or more) 'watch' systems that allow me to grade long distance route metrics using something simple like we have for gateway monitoring.

Is there a way to leverage existing gateway setup / RRD graphing for this?  I don't want to add bogus gateways to do this though, but if there's an option there that permits adding some that will never be used for this purpose is it possible?
