Topic: customoverlay, like clockoverlay, but more flexible

Question:
Is there any way to add a custom overlay on every widget, like the clock overlay, but something else?

Reason:
I would like have a simple RED/GREEN dot monitor (would settle for text), so that I can monitor a Nagios system without having to load a Nagios widget and leave it on all the time. I'd rather run the grandkids flickr stream, or some news channel, and just have the Nagios indicator as an overlay, along with the clock overlay, or instead of..

Re: customoverlay, like clockoverlay, but more flexible

okay, chumby is already running #! date "+%%%", based on the overlay.xml, so couldn't it take another <foo>bar.php</foo> in the same or a different file to enable some alternate overlays.

What service/process reads and parses the overlay file?
