All,
I don't know if the topic has come up before, but couldn't the IBIS
committee
give the source code to institutions of learning for free without giving
them
a license to distribute it or its derivatives? If some student or
department
develops something neat and wants to go public with it could they not come
back to the committee for permission? As bad as having to ask permission
sounds, remember that an updated version of s2ibis got cancelled because it
competed with commercial software.
Best regards,
Matthew Flora
