We are planning to use dbus in our organization. While we were analyzing the licensing of dbus and some of the files inside, we got some questions. It would be very helpful if you could help us to clarify some of our questions. The following are some of concerns and queries.
It is mentioned in 'COPYING' file that
'D-Bus is licensed to you under your choice of the Academic Free License version 2.1, or the GNU General Public License version 2 (or, at your option any later version).'
Since it is mentioned 'your choice' in the sentence, we are free to select Academic Free License or GPL V2 or later license (we choose Academic free license in order to avoid copyleft effect)
The following is mentioned in some files:
a)' Licensed under the Academic Free License version 2.1' and 'This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or(at your option) any later version.'
b)'Licensed under the Academic Free License version 2.0' and 'This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.'
c)'released under the D-Bus licenses, GNU GPL version 2 (or greater) and AFL 1.1 (or greater) without wording 'your choice' mentioned in the above sentences.
Should we consider both the licenses or is there a chance that the wording 'your choice' was missed out? If we consider both licenses, the GPL license will be automatically selected and it will lead to a copyleft effect. The list of the files having both AFL AND GPL license are mentioned in the document embedded in this email:-
It is mentioned in 'COPYING' file: 'switch to Academic Free License version 2.1 instead of 2.0, to resolve complaints about patent termination clause. Can we select Academic free license V2.1 instead of Academic free license V2.0.
It is mentioned that Communications Engine (Ice)</a> is a powerful IPC mechanism more on the level of SOAP or CORBA than D-Bus. Ice has a "dual-license" business around it; i.e. you can use it under the GPL, or pay for a proprietary license. Can you please explain about this ' pay for proprietary license' option?
With best regards,
