Michael,
I'd like to take credit for the idea, but it's not mine actually. When I was initially seaching for MindMapping software I tried briefly some of the online services. The Vista Gadget Tie-in is already implemented with http://www.mindmeister.com/.
As a result of this being a free service in other places, I would be interested in paying for it for MindManager (Lite), but not beyond 10 euros or so. I'm currently using the Lite version of MindManager as a stepping stone to the Pro version, assuming all works out well. I believe such an add-on should come included with the Pro.
Thoughts welcome!
