 in the specific case i brought up, there are further conflicts which i 
 had not thought about before. the name of the project, zotero, is 
 trademarked, but all parts of the project are released under free 
 licences. the conflict is that some of the code uses the word zotero, 
 and thus i suppose can't be redistributed without changes. similarly 
 file and folder names, and the trademark owned by the various sponsors 
 (a university and other similar academic groups) will be similar as it 
 is embedded in various places such as the 'about' dialogue. apparently 
 re-distributors are forbidden from bringing the name of sponsors into 
 disrepute. also, there are icons and other images which contain the name 
 of the project. so, it conforms to free software, but due to the 
 trademark, we can't exercise all the rights given to us under that 
 license.

 an odd anomaly, one strand of IP affecting another. i wonder what the 
 complete, technical, legal stance is?

 or am i finding something that isn't there?
