Youtube Blocked At Your School?

I have been using Splicd.com to quickly show only the portion of a youtube video I want in class. It is great for schools where youtube is blocked.  But two others that you can use are ViewPure and SafeShare.tv which also give you a new url which will get you around the block your school may have.  I found these last two at a new blog I follow called "The Pursuit of Education Technology Happiness."
