I have blown this old post away:

I have deleted code for this tool and rewritten from scratch.
I have a problem with textarea tag in that it put breaks in the text area. Sorry about that. Until I get that fixed you will need to just to do a search and replace. The tool will allow that admin to right click and force an action on a collection or single computer. Unlike other tools for policy and inventory I don't kick the inventory key forcing the machine to do a Full inventory. I kick off a standard Inventory so it will be a delta and fast.
