I teach Multimedia Design and will be adding a Video Production course. Plus, we are starting a school "TV show". I have came across phpmotion, kaltura, and now the wordpress video framework. I want some sort of "youtube" type functionality. I have a 2.8 Ghz quadcore xeon Xserve in my class that is the Web server. I know in an ideal world there would be a separate server for processing video.
What solution would work in a setting like this? I am not a super guru, but I am figuring things out as I go.
