Well... that WOULD solve the license issue. A few things I'd like to
point out about using the NSS, however:
-- NSS requires the Netscape Portable Runtime (NSPR) as well as the
Netscape Build Environment... This would make it somewhat more
complicated to build the emulator.
-- I know that FreeBSD ships with OpenSSL. I believe the Linuxes do
too... So setting up OpenSSL is a non-issue for us Un*x people.
-- To build NSS on Windows requires both Cygwin and MS Visual C++.
Cygwin isn't that big of a deal, it complicates the setup
instructions but at least it's open source. MSVC however is
not. It's at least USD$ 500!
-- I'd have to re-write sslstream.c completely (which isn't that
big of a deal) and I'd have to make the win32 code work with
MSVC (unless, of course, we wanted to require both MinGW and MSVC)
So... wow, that adds a lot of extra work in setting up our build
environment. And makes our free emulator somewhat expensive for Windows
users.
All this because we love the GPL so much?
