Hi Drupalistas!<br><br>This question has come up a couple of times in our local Drupal user group meetings, but the answer that was given didn't sound quite right to me:<br><br>If I code a module for Drupal, does it -have- to be GPL? That is, is a module considered a 'derivative work' of Drupal? Or is a module considered it's own entity from an intellectual property standpoint (that is, can I use something like <a href="http://www.raizlabs.com/software/phpobfuscator/">http://www.raizlabs.com/software/phpobfuscator/</a> to obfuscate my source code and sell my module without licensing it as GPL?)<br>
<br>Because a module executes as a part of Drupal, must it be GPL?<br><br>Taking that further, can we apply the same question to things like the Linux kernel? Is a kernel module required to be GPL? Can I sell a proprietary kernel extension?<br>
<br>Thanks,<br>Cameron Eagans<br>
