This was my impression of GPL too.  I thought that's why the LGPL (?) was
created.

This is unclear, and sounds like hair splitting to me.  What's the
difference between linking and using a plugin?  What happens when
the plugin is a dynamically linked shared library?  I haven't seen
PoPy, but if it's a C library interface under Python (like Pygresql)
the chances are good.

Confusion reigns.
