No-installation license?

Please think about making some kind of license where you (site owner) can purchase for your staff (coder) to particitate in paid members forums on (especially Add-on Development forums). It will not be possible for them to download code or install the software anywhere.

Or maybe you can offer a premium license where the holder can assign several accounts on as their coders so they can participate in developing add-ons, looking at tutorials...

Thank you.
