Site modules block

I'm thinking of a simple module for demo sites that would provide a block(s) that list which modules are in use on the site. Site admin could choose which modules to list (or all), and associate them with the module or feature being demonstrated.

The block would show the module versions being used (or package date for dev modules), whether they are dependencies for the features, and link to the modules' project pages.

Basically, it saves the site admin from remembering to update info about the demo site, and lets users know which versions of dependencies are compatible.

Something like this:

----------Block-------------
My Demonstration Module

This site demos my module, which does X and Y.

This demo for My Module currently uses these required modules:
CCK Version#
Filefield Version #

This demo for My Module also currently uses the optional modules:
Token Version#
Filefield Paths Version #

----------End Block------------

Thoughts?
