Lol. That is not going to happen. When I was working on a project that required access to the Windows source code, the security hoops I had to jump through were ridiculous. Can't see them abandoning all that nice security machinery.
Actually, I worked in such a project a long time ago and I had the opposite feeling. They just gave us a few cds with the code on it. There were some restrictions as who could use it and so on, but it seems they didn't really care.
Lucky you. We got RSA tokens and devices and software so that we could connect to the Redmond server where the stuff was hosted. Copying it from that environment to your own was NOT ALLOWED.
