Please don't use the word "tainted" about standard open source licenses,  
you're just doing everyone in open source a disservice.

BSD/LGPL license is a more likely candidate. License proliferation is a  
problem, and we're trying to work with as few (and widely accepted)  
licenses as possible. ZPL is not one of these.

Anyway, the only reason plone.folder is under GPL at the moment is because  
nobody has asked us to do anything about it yet. If you're interested in  
using the plone.folder code, I'm sure we can make it happen. We need a  
first case to push a general policy. It has been discussed extensively in  
both the community and on the board, and everybody agrees that certain  
components should be BSD or LGPL instead.

PS: it's unlikely that the license boundaries will be on plone.* vs.  
plone.app.*. As a general rule of thumb, I think it's close to correct,  
but the naming isn't about licensing. We might have components that have a  
good reason for being GPL that will live in the plone.* namespace.
