Hi Thad,
Yup, I'm sure the ability to ping off-campus will be a step in the right direction! ;)
You might want to take a look at this document, and/or send it along to your networking staff:

You're right that just asking for multicast isn't enough detail -- there are real issues with port access that will likely be an issue if you're behind a firewall. Many of us end up in the DMZ as a result, though there are other successful approaches.
Cheers,
Jennifer
