Sorry for the late reply on this one; I'm just back from vacation.

What innovative (re)uses of Wikipedia or Wikimedia content are out there?
One interesting one is freebase.com. (Disclaimer; I have pals who work there, and have done some work for them myself.) They are calling themselves a "data commons", and are importing information from a number of open sources and turning it into API-friendly structured data.
Unfortunately it's in private beta right now, but I have a couple of spare invitations for people who are likely to be either active contributors or active API users and would give them good feedback.
I'm seeking permission to license images I have of NHL trophies under GFDL or compatible license. I'd like to give them examples or explanation of positive benefits of such licensing and reuse of content and the philosophy behind it.
Part of the magic of an open content license is that you don't know quite what people will do with this. The Wikipedia-on-DVD and the One Laptop Per Child projects are great examples of how your info might be used for public benefit.
With Freebase, the notion is that people will be able to easily build data-driven sites. So for example some hockey fan might build per-team discussion areas or some cute fan game using the open content. Perhaps it would end up in a kiosk at a hockey museum.
Hoping that helps,
William
