It's ok :P At least I know where you are standing. I do not totally disagree
with LGPL, but I would much prefer switching to ASF instead. I can't force
the developers to accept the license I would like, but I'll try hard to make
my point and convince you guys that it is for the good of the project.

Currently, there is pretty much rdesktop or rdesktop derivates, and rdesktop
is not modular and entirely GPLv3. If people have doubts, they don't have
much alternatives to go in the open source world ;) Also, we're going to
have NLA support in our next release, that's major.

No, it might not have such a bad chilling effect, but I see a bit beyond
that: I would like RDP to compete with VNC in terms of popularity. VNC is
mature and widely used, and it also has implementations in a wide variety of
licenses. If we go for LGPL, we would give a reason to exist for
implementations in more permissive licenses.

The modern datacenter depends on network connectivity to access resources
and provide services. The best practices for maximizing a physical server's
connectivity to a physical network are well understood - see how these
rules translate into the virtual world?
