Why does ivata groupware use a dual license strategy for source code?
Dual licensing of the ivata groupware source code provides open and free access to the technology both for the GPL community and for other developers or companies that cannot use the GPL. We use the same practise as other open-source projects like Perl, OpenOffice.org and Mozilla. It lets ivata offer commercial versions and makes sure ivata will be able to defend the GPL license, if necessary.
