Does a copy of Spring exist somewhere? For reasons I no longer
remember we failed to get a copy after talking about it when I worked
for Carnegie Mellon (it certainly wasn't an issue of money or
licensing; we had Solaris 2.4 source, for instance: i was the keeper
of the CDs)

I vaguely remember Bryan saying he had a copy like 5 years ago but I
don't recall anything coming of it.
