David, you should submit your request as a product suggestion on
Connect. Seriously. If you feel you need that level of monitoring, probably others do as well. And the only way you're likely to be able to get it in a truly useful fashion will probably require changes to Windows Home Server to capture additional information and expose it through the SDK for add-ins to use.
That said, I honestly doubt that anything will make it into the product to support this. I think you're looking for significant added complexity, because if you have the ability to monitor this sort of information, you probably also want the ability to throttle use if certain parameters are exceeded, and that is kind of counter to the concept of Windows Home Server.
I'm not on the WHS team, I just post a lot. :)
