Is there a ready-made license for "we will provide you the source code which you may modify, but you are 't allowed to redistribute it"?
At work I'm purchasing a piece of hardware with a long service life and I'm trying to negotiate that I should be provided the source code to the semi-embedded computer. The reason should be obvious--so that we can audit the code, fix bugs, or add features without being dependent on the continued existence and good faith of the vendor. The roadblocks are actually coming not from the vendor but from our own purchasing department who are ignorant of computers and terrified of anything different.
Is there existing licenses or legal precedents I can cite that might help convince our purchasing and/or legal departments? They all think source code is a magical incantation and that looking at it will summon lawyers. I'm trying to make the case that it's similar to any other copyrighted work and can be releases under any number of licenses.
