It could be as simple as querying the backend API.

$ curl http://<backend_ip>:6544/Status/GetStatus

Returns data *only* in XML, of the backend status
(we are working on a proper endpoint that can return
the data in the format you request)

There is also

$ curl http://<backend_ip>:6544/Status/GetStatusHTML

This returns *only* html and is used by both mythweb
and the "webfrontend"
