We don't have the means to "share" the dashboard out of the web interface. For what you're looking to do, in v8.x, we would get you to use custom reports (totally tweaked) and a report scheduler that saved the report to disk at specific intervals.
Give the reporting thing a try, and give me the weekend to think about your want. It might be possible. :)
Thanks for the prompt reply!
I forgot to mention we're using version 9.
Publishing it disk at intervals would work too.
Apparently Apple has a system status on one of their webpages and that's where we got the idea; it looks very similar to our dashboard in v9.
