Right now you can get away with a lot of "oversubscription" in MDU situations when you have 1-2Gbps to the building (typical millimeter-wave radio speeds). I wouldn't be surprised if they have buildings fed with 1x1Gbps going to 40x1Gbps clients. (hand waving about Erlangs and queuing theory here) E.g. if you assume everyone is downloading a DVD image from a fast mirror (CentOS install DVD or something), they probably won't all start the download at the same time so there's a really good chance one user will finish their download before someone else starts theirs. My MDU users rarely crack 1Mbps on a 30-day 95th percentile basis.
