I have decided to offer the different Creative Commons licenses as an
option on Internet-Encyclopedia and have changed the notice at the bottom
of the page to this:
"gnunote" => "Unless some other copyright license such as one of the
<a

licenses</a>
has been selected by the original author of an article all text is
available under the terms of the <a
href='http://www.internet-encyclopedia.org/wiki.phtml?title=GNU_Free_Do…

restricted, check the description of the image for details.
This should allow the use of the Public Library of Science articles and
material available under any other licence including material available
only for non-profit use or otherwise restricted available for use.
As to whether Wikipedia should make a similar change...
