Hi again, Ok, so the license is available at
http://www.bio.cam.ac.uk/nmr/ccp/project/about_ccpn/licensing/licensing.html Unfortunately, this looks quite incompatible to the GPL: (2) Conditions for DISTRIBUTION of SOFTWARE to MEMBERS (2.1) An individual or ORGANISATION must be a MEMBER of CCPN in order to receive any SOFTWARE from CCPN, and must adhere to the MEMBERSHIP, DISTRIBUTION and RE-DISTRIBUTION rules. Under these conditions, any previously DISTRIBUTED SOFTWARE may be used in for the lifetime of the SOFTWARE even if MEMBERSHIP of CCPN lapses. (4) Conditions for MEMBERSHIP of CCPN MEMBERSHIP for an individual or ORGANISATION shall be based on registration and payment of annual fee as required and detailed below. The annual fee may be reviewed from time to time. The current scale of fees are as follows: a. individuals and not for profit ORGANISATIONs - nil b. ORGANISATIONs with annual turnover less than 200000 pounds Sterling - nil c. ORGANISATIONs with annual turnover between 200000 pounds Sterling and 1 million pounds Sterling - 1000 pounds Sterling d. ORGANISATIONs with annual turnover larger than one million pounds Sterling - 7000 pounds Sterling This makes the software not freely distributable, IMHO Furthermore, it violates one of the definitions of Open-Source Software, namely 'No Discrimination Against Persons or Groups', see http://www.opensource.org/docs/definition.php. Please correct me if I'm wrong. thanks, Michael
