I would advise against reimplementing functionality found elsewhere in 
proven code, esp. if it has nothing at all to do with GUIs. In this 
case, I'd expect any such implementation to be a thin wrapper around 
libgcrypt, the latter being the cryptographic core of GnuPG extracted 
into a library (a LGPL one, I might add). The more so as gnutls and 
gsasl both use it already for their cryptography needs and I for one 
will make kdesasl a thin wrapper around gsasl in 
KDE(3.2).nextRelease().

It has become fashionable in the post Cold War world to label
opponents as terrorists [...]. By doing so, the authorities instill
within society a culture of fear, leading people to accept that their
rights (and the rights of others) be trampled on for the sake of the
common good. In other words, it justifies the loss of privacy and a
state of surveillance they would otherwise not accept. Both communism
and fascism were examples of this technique used to perfection.
