i am well aware of the credits/advertisements clause.  it is not part
of gzsig's license.

yes, when i write code i want people to use it.  i want it to be
useful, new technology, and therefore i don't mind if large companies
use my code in properietary software.  if they are not giving back,
they are the ones who lose out on pushing their new technology.  but i
also understand that in order for many companies to survive, they have
to make some of their technology propertary also, eventually everyone
has to privde bread and butter for themselves and their families.
that's why i think the LGPL is at least a step in the right direction,
but so far, in my opinion, the BSD style licenses are the best (i
don't personally care much for the credits clause).

as for easy-to-include cryptography, do remember openssl with their
libcrypto.  it has become quite polished and easy to use.  openssl is
dual licensed, and both of them are BSD style.  so i don't think
anyone is getting an advantage like you claim.  gzsig uses openssl's
digital signature mechanisms for both DSA and RSA signatures, but it
lacked PGP support which i found handy.
