The FSF just released GNU Affero General Public License Version 3 yesterday, Nov 19 2007. All of my AMXX projects will now be released under this license. The following is an excerpt from the FSF sites press release at http://www.fsf.org/agplv3-pr:
The GNU GPL allows people to modify the software they receive, and share those modified versions with others, as long as they make source available to the recipients when they do so. However, a user can modify the software and run the modified version on a network server without releasing it. Since use of the server does not imply that people can download a copy of the program, this means the modifications may never be released. Many programmers choose to use the GNU GPL to cultivate community development; if many of the modifications developed by the programs' users are never released, this can be discouraging for them. The GNU AGPL addresses their concerns. The FSF recommends that people consider using the GNU AGPL for any software which will commonly be run over a network.
