I have a widget like this for AWS+Virtualbox, it sorts all instances across all regions into tag name groups, by ip, by region, and by instance type. Unfortunately I know it only works for Windows and linux at the moment and my company hasn't given me a green flag to release it.

Still this project is a lot prettier and appears to have been more refined while mine was hobbled together in a hour or two and fit in one Python file ( reasonably, its not 10 files in one ).
