Tom or Gavin would probably be the best people to ask about how that works though. :)
One other thing that I don't think has been mentioned is the copyright of the videos themselves. IANAL, but don't you have to get permission from the person/company that created a particular video before you can do other stuff with it e.g. converting and/or uploading it to another webhost?
Also, if you need a way to organise your educational YouTube videos you may want to look at MediaCore.
