OK, so you want to ustream from school but don't want everyone in the world to be able to see it... ustream now allows you to password protect your shows. Just remember, if you archive it, you can't edit it so if the password gets out, you'll need to change it, I guess.
It is better, however, I'm going to have to test it a bit so that I can tell you more.
Meanwhile, here is Will's post about it.
