So I got curious and checked the 'current' list. Looks to me like the
question revolving around MIT is small potatoes compared with some
other organizations ... HP now owns two /8 blocks ... their own and DECs.
HP is down a total of four /8's from the early days.
Including the /8 they picked up from DEC.
A bunch of IANA reserved ... which seem likely to be available.
One would expect the IANA reserved blocks (that are actually
useful) will be handed to the RIRs as per current policy.
I'd bet more than 3/4ths of the space allocated to specific organizations
as /8s could be recovered. If that needs to happen, the sooner the current
owners of those blocks start planning, the easier it will be.
been there, done that. times and circumstances change and
recovery these days is likely an exercise is futility.
the -LARGEST- assumption that most folks make is that if they
can't see a prefix in their tiny, constrained view of the Internet's
routing system (e.g. a subset of the commodity users of IP) that
said prefix is fair game for recovery - to be re-assigned to folks
that they can see through their routing porthole. That assumption
has always proven false ...
Those who speculated that MIT had a fundraising opportunity neglected
to comment on the competition.

So to answer your question about what is stopping the RIRs from
reclaiming the very earliest /8 allocations, it isn't yet worth the
bother. Some of them have been returned voluntarily as you can see if
you compare http://www.iana.org/assignments/ipv4-address-space with RFC
739.
