[Notion-devel] Using an LGPL license extended with additional terms

[Arnout E. <no...@bz...>]

Hello,

I'm writing on behalf of the 'Notion project', which is a group of people 
intending to fork/adopt the 'Ion' software. We'd like to get the licensing 
right, and have some questions.

Unfortunately, the code is released under the LGPL extended with several 
non-free clauses, and the original author is unwilling to change this. The 
license can be found at http://arnout.engelen.eu/files/dev/notion/LICENSE-ION 
and it is attached.

Question: is legal at all to use this license, in particular given the answers
found at http://www.gnu.org/licenses/gpl-faq.html#ModifyGPL and
http://www.gnu.org/licenses/gpl-faq.html#NoMilitary ?

Question: is it legal to take new LGPL'ed files, add them to Notion, and 
redistribute the result under the 'LGPL-extended'? 

Question: would asking contributors to dual-license their contributions under 
both the LGPL and the 'LGPL-extended' (and licensing the result under the 
'LGPL-extended') be acceptable?


Kind regards,

Arnout Engelen
