I don't see that.  The web app gets run by Karrigell like a CGI script
is run by Apache, like a Linux app is run by the Linux kernel.  The
Linux kernel is GPL but that doesn't mean every Linux app that calls
through the kernel through its documented API is affected.  The Linux
kernel GPL only comes into play if you start modifying the kernel, not
writing programs that use it.

There should be no exclusion.

The LGPL has fallen into some disfavor at the FSF, and I don't see
Karrigell as a library.  The application is not an integrated blob
combining Karrigell and user code, from what I can tell.  Rather, the
user code is run under Karrigell's control, like Karrigell itself
is run under the Python interpreter.

But that doesn't gain the community benefits of the GPL since it
foregoes the possibility of users improving Karrigell by incorporating
other GPL'd code into it and distributing the improved version.
