I don't think university-like organizations ever need more than a /48. One and the only really problematic thing is if they provide access to students/staff/etc., e.g. via DSL, dial-up, dorms or what. /64 would usually be ok (except very large universities and the like), /48 would not.
Universities are ISPs, and it is perfectly legitimate to assign /48s to students. Invariably, each class I teach IPv6 subnetting, students ask me "ok, now what if want to try this?" and my answer is "go to freenet6 and get a /48". Yes, they're going to use only two or three subnets possibly with only with one host each but they do need more than a /64 and I do not think that allocating anything between a /48 and a /64 is debatable at this point. => 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... So universities can't be real ISPs by them selves, and to come back to the first topic, if you are an ISP or an ISP-like organization with a 2 year plan for 200 or more IPv6 /48 customers, the 3 BGP peers with the default-free routing table rule should not be a problem. The real problem is today an organization is supposed to be "large enough" to get a sub-TLA from its RIR or to be connected to such an organization which delegates a prefix. The case where the organization providing the connectivity doesn't provide a prefix too is both against the ideas of "IPv6 Address Allocation and Assignment Global Policy" and perhaps its letter.
