Unfortunately, the API calls aren't the same.  If you use a different API,
you need to call different functions and take different steps to make
the SSL work.

Furthermore, until recently SSL wasn't included in the base OS.  Now,
the OpenSSL package is included with *BSD, and at least RedHat Linux.
Are the others all the same? I don't know.  I know that Windows isn't
the same, and not all versions of Windows come with an SSL API.  OpenSSL
compiles & works on every operating system that we need to support.  It's
a powerful API, and it's open source.   Operating systems that don't come
with an SSL API can all get OpenSSL for free and install it.  It sure
seemed like the right choice!

Well, it couldn't just automagically work with any SSL API, for the
reasons explained above.  The SSL part of it could probably be distributed
as a seperate DLL that could be included / not included at run-time with a
little work.

That might actually solve the license problem, I'm not sure.

Unless I'm confused, this is all getting blown way out of proportion.  All
we really need is to get the copyright holders (Mike, Jay and myself) to
add the following clause:

   "This program is released under the GPL with the additional exemption
that compiling, linking, and/or using OpenSSL is allowed."

That's up to you. :)
