=> one detail which is never called to mind here is an university which gives internet access to its students *outside* the university (i.e. in a context where students can need a /48) should be sued by all commercial ISPs for illegal competition using public money...
I think most NREN AUP's make this sort of activity unlikely => with a strict or really enforced AUP the network can become near useless (at least for students who have extra-academic interests :-). So usually the AUP is loose or not really enforced *and* a commercial ISP is implied into the MAN/WAN infrastructure and management. IMHO this is the least bad solution because the ISP has technical and man-power capacities which are not usual in an university and never in its missions. On the other side the ISP gets "subsidized" customers... certainly in the UK you can't generally run commercial services over JANET, and you certainly can't resell academic bandwidth to external users. => I shan't ask details about "generally" and "external" (:-). An interesting question is whether the types of devices that become deployed in campus departments keep the routing hierarchy similar for IPv6 as IPv4, or whether we'll see devices that offer a /64 per office, for example. => in the campus or the university LANs are better (easier, cheaper, etc) so I don't believe the issue exists.
