Considering a licence change

Hi Contributors, I'd like to open a discussion about a licence change. I've been thinking for a while to open up the licence more. Currently the code is GPL which allows end-users (including commercial companies using XWiki internally or for their web sites) to use XWiki without being required to contribute code back, but requires software distributors to contribute all modifications using the GPL. Until version 0.9.543 there was only code from myself in it which allowed me to double licence code, which has been done with one company in the US who has embedded XWiki in a proprietary product. Starting with release 0.9.793, XWiki has significant contributions from other users which if we want to be able to allow this company or others in the future to use XWiki in compliance with the open-source licence we need to: 1/ Either get the right from ALL contributors to allow XPertNet to double-licence the contributions for proprietary usage and charge for it as well as support. 2/ Open up the licence to a licence which would allow them to do it without a double licence. This licence could be LGPL or ASL. Customers could still take a support contract with XPertNet. I'd like to hear the opinions of everybody and of course especially of contributors who have commited code to XWiki. Which route should be go from your point of view and are you willing to relicence your code to any of the licence proposed (giving the right to double licence, changing licence to LGPL or changing licence to ASL). This question is also true for Jens who has contributed the Lucene plugin and the email notification plugin but to a lesser extent as these are plugins and could keep a separate licence. It would just restrict specific usage of these specific plugins. Whatever we decide, we will need to create some documents that contributors would sign to specifically accept the conditions under with the contributions are made to the code base.
