I have since downloaded the debian bundle and taken a look at the
licenses.  FTR, I did neither install nor use the software.  I simply
extracted the archive and the debian packages' filesystem tarball to
have a look at the licenses.

The network plugin is licensed under the AVASYS PUBLIC LICENSE and the
AGREEMENT.  Both licenses are mentioned for Image Scan! for Linux and
definitely non-free and GPL incompatible.  I understand that Image Scan
v3 runs these plugins in separate processes to avoid a GPL violation.

I assume that you just forgot to add these for Image Scan v3 when you
added the plugins to the "bundle".  You can easily fix that by adding
them to the list of licenses for Image Scan v3 on [1].

# I and many others would much prefer to see these plugins released as
# Free Software, though.
