I think you need comments from lawyer here.
My opinion is - license is applied to "end product" - doesn't matter
if it is executable or library.
According my understanding, if end product (executable or library)
contains only headers from GPL 2 product, then end product can not be
GPL 2 product.
There are some restrictions - I mean non GPL product must use only
structures - then it could be non GPL product.
Asterisk is GPL product and it can use non GPL codecs (which are libraries).

Hello Olle,
A very interesting and important question.
As maintainer and developer of app_python (and upcoming app_java), I'm a
very interested in this question.
I just looked for python's licenses (http://docs.python.org/3/license.html).
Since app_python offers a correct work >= 2.4.3 (at least was tested a week
ago), it's should be licensed under PSF license.
PSF is also GPL-compatible license.

GPL-compatible doesn’t mean that we’re distributing Python under the GPL.
All Python licenses, unlike the GPL, let you distribute a modified version
without making your changes open source. The GPL-compatible licenses make it
possible to combine Python with other software that is released under the
GPL; the others don’t.

Hello from North Carolina where SIPit starts tomorrow!
Reading through the docs on the app_* modules I wonder how the GPLv2 is
handled here. By default, GPL is sticky, so any module linked in to Kamailio
will be GPL-licensed.
With app_mono, precompiled binaries are executed within Kamailio, but not
"linked in" to the core. The question here is if we have a clear distinction
here. If someone developes a Kamailio-based appliance and sells it - would
the customer have the right to app_mono modules under the GPL?
What about python, java and Lua? I don't think these environments
precompile, but they still execute within a GPL environment.
I think we need a clear statement about this in the README, like Asterisk
has for AMI/AGI applications.
Greetings!
