Kaltura: Video Collaboration Services Partnering with Wikipedia

I read that the Kaltura video collaboration site is partnering with Wikipedia. I took a look at some of the kaltura videos on the site. Quite honestly, I couldn't figure out how to determine which ones had multiple contributers (or if any had more than one video clip contributor). That said, if this thing works (I haven't signed up for the service to upload anything), it would be interesting to see compilation kaltura video collaborations from family gatherings, conferences, sports events, etc.
