[Opensim-dev] service monitoring for opensim

[Brianna]

Be creative with PHP, after all it will read a sending script from the 
region and the opensim log is on the server as a file and can be parsed to 
do about anything.
My point is there is enough work for the coders and loops for the simulator 
so get all that data you will never read away from opensim and let the web 
side work it's arse off.

seems sane to me at first glance at least..

yes, and i figure rest / http is good for that.
