I've been following recent discussion on WikiEducator about collaborative video editing. The service has been made available using technology from a company called Kaltura. I haven't actually played with the software - I just haven't had the badwidth while on the road. But it seems to be a positive development and appears to have been very enthusiastically received by WikiEducator members. More from Webb Alert. If you want to learn more about WikiEducator, you can attend an online workshop January 28 - February 8.
