if this is the coral that I'm thinking of (coral distrubution network or some such garbage) then it's basically a poor mans akamia. They're not goign to be /.'ed any time soon.

That bandwidth is paid for by state taxes and student tuition, all that good stuff, and should most definately not be going to fund a commercial enterprise like slashdot.
