The Kabsch and Sander program DSSP is available:  I located it last week
using GOPHER to reach the EMBL Heidelberg server, and located the 
software/unix directory.  A dssp directory contains a license agreement and
a README file.  Retrieving these, printing and signing the license agreement
and FAXing it to the address given resulted in EMAIL distribution of the
dssp sources the following night.  The program has compiled and appears to 
work fine on the example file given.
