As long as the use was strictly internal to your organization the only people you'd have to give the source to would be the users. This includes 3rd party companies you might have a business relationship with (though I doubt they'd put such a pressure on you =). The bigger concern with such an integration is if it ever gets exposed to the Internet at large. Then you'll need to distribute the source or be in violation. Why risk it? Licenses will be pretty cheap for such one-off situations. Everything is negotiable regardless. -- Dan McDougall - Author of Gate One
