[development] The OSI Artist License compatibility with GPL

Does anyone see any reason why something licensed with the OSI Artistic License (http://www.opensource.org/licenses/artistic-license.php) can't be distributed in a GPL'd Drupal module? After perusing the text of the license briefly, I'm not seeing anything that would prevent it - but I may also need to read further in the recent GPL-compatibility thread (which is ginormous, by the way!). Thanks, Jeff
