All the software modules in the system (about 20 of them) have license text at the top, reproduced below. There's also a separate file LICENSE.txt in the project space (next to README.txt file and INSTALL.txt) with a separate copy.

The MIT license I use is less restrictive than the CC licenses - you can take the project and use or modify any portion of it for any purpose without notice.

For anyone at a company whose lawyers have any doubts, drop me a note and I'll E-mail back a specific waiver granting your company free and open access to the project.
