I realize I am wordy, but four bullet points (one of which involves
apparel) != "17 pages of caveats".  Nice try.  The rest of the email was
inline replies to Justin's points.

Have you ever been involved in University space wars?  Especially in a
new building?  The 9-layer OSI model gets pretty top-heavy when you
factor that in.  If anything, the caveats helped to keep others from
wanting to use the space.

But I will say that the general difficulty of getting equipment in and
out of the CEVs generally discouraged UCB from doing more CEVs beyond
the 3 originals.  That _one_ caveat weighed pretty heavily.
