*Users* are the key here, the only way the gpl applies is if they try
to bundle their extension with blender proper (or use gpl'd libs). You
can take your copy of blender and link it to whatever you want (as in
the 'internal tools' example given previously) and developers can
release their independent code under whatever restrictive license they
chose.

The proprietary extension links to BSD headers and implements the
'external' interface, Blender links to BSD headers and implements the
internal interface and the user does the 'aggregation' in the privacy
of their own home. Easy peasy...
