I agree, I just didn't want someone to get a false sense of security. Too 
often we are asked for a technological solution to a non-technical 
problem. (OT: Our librarian wanted us to turn off the ability for students 
to change their desktop background. I wasn't going to punish the entire 
student body just because some of them chose inappropriate backgrounds. We 
just disable their account if they are caught with an inappropriate 
background (covered in our AUP).

Even blocking everything and transparently proxying those two ports won't 
stop someone from running some sort of anonymizing proxy such as 
circumventor.

But I agree, talk softly but carry a big stick!
