You are indeed under the same rules as the internet laws, if you broadcast music without permission from an artist, you are in fact breaking the law. If you utilize a network without the owner's permission to transmit your stream, you in fact pirating, sorry man, but bandwidth isn't cheap. And if the school owns the network, and has rules against consuming bandwidth for a server, you are kind of in a pinch. The fact is you really should have consulted the IT people and administration about your ideas to run a campus only station. I am in the midst of doing a similar thing on a community college network, but it will be completely run by the college, as it should be, it's their bandwidth/money isn't it?
