The Affero General Public License ("AGPL") has been approved by the OSI. The AGPL is an important option for companies whose software can be used to provide a service. It includes a "network use" provision which requires that the source code be made available to "users" of the service. For a more information about the AGPL, you can read my earlier post. http://lawandlifesiliconvalley.blogspot.com/2007/11/free-software-foundation-announces.html
Thanks to Funambol for submitting the license to the OSI and following up. http://www.funambol.com/blog/capo/. OSI approval is important for adoption in many large organizations which use OSI approval as a basis to approve the use of software distributed under such a license. I am particularly pleased that OSI adopted AGPL because Fabrizio Capobianco at Funambol and I have a bet about whether GPLv3 or AGPL will be the dominant license in five years. He can no longer complain that it is not a level playing field! So consider AGPL, but remember I have money riding on your adoption of GPLv3.
