Anonymous remailers

I have a question for all the 'punks who are running remailers. I've noticed that most of you run the remailers from your accounts at various colleges & universities. I want to know what kinds of reactions you got from the system administrators. Did they ask lots of questions, give you a hard time about it, or not care? (or do they not know?) Has anyone been forced to shut down their remailer? I know some guys got hit with a lot of flack over some pgp keyservers, has anything similiar happened with the remailer system? Also, if I was to try running a remailer, would I need my own machine, or is there some way I could get the school's computers to run the remailer for me? or does it vary by system?
