While i agree with Harald's goal of making network operators of public networks publish their changes (and that the GPL alone does nothing here), I'm not sure using the AGPLv3 for that is straight-forward. I don't think the GPL uses "modified version" in the sense of "different from mainline", but rather every change to the source code creates a new modified version. So publishing the source code or having the changes merged to some mainline version does not remove the "modified flag". So every developer would be running a modified version and so be required to follow Section 13 by informing all users directly. Instead, we could add an additional permission the the license statement, which allows everyone who would need "prominently offer the source all users" to *instead* fulfill this requirement by publishing the corresponding source on their website. We could also ask (but not require) them to notify the mailing list. > a) Do you think re-licensing to AGPLv3 is a good idea? As above, i fully agree with your goal. But I'm not convinced yet. Also, the GPLv3 has changed how it relates to Patents, which may be relevant to a lot of GSM work. I can't say i understand what Section 11 really means for network operators. Their lawyers may decide it's too risky and not use OpenBSC/Osmocom. > b) If you have contributed, would you re-license your code under AGPLv3? You obviously have vastly more experience with the GPL, so I'd agree to re-license if you think everything will be fine. :) Best regards, -- Jan Lübbe <jluebbe at lasnet.de> http://sicherheitsschwankung.de gpg-key 1024D/D8480F2E 2002-03-20 fingerprint 1B25 F91F 9E7B 5D4F 1282 02D6 8A83 8BE4 D848 0F2E
