For TCPDF - it might depend on the details, which I haven't researched, but most likely not. Even if FOSS, this is, to me, an illegitimate use of LGPLv3 with a noncustomary additional restriction, even if it is not a violation of any upstream LGPL license. This reminds me of iText, another PDF-generating library, recent versions of which purport to be under AGPLv3 plus a similar restriction. AskoziaPBX is clearly not FOSS, as it requires "prior written consent" for commercial redistribution. The intended license of Roundcube skins/plugins seems OK (GPL plus additional permissions [or copyleft clarifications if you prefer]) but could probably be drafted more clearly. I couldn't access the sipfoundry.org site, but I'd consider the quoted provision enough to make a license non-FOSS. - RF _______________________________________________ License-discuss mailing list License-discuss@opensource.org http://projects.opensource.org/cgi-bin/mailman/listinfo/license-discuss
