What is technet subscription all about?
Will it give me a license for an o/s, vs.net for use in production for "free"?
How does it differ from MSDN?
This link (http://ladylicensing.spaces.live.com/Blog/cns!87F95F1B5B21B01E!1241.entry) has more information (This is the blog of Licensing Escalation Manager at MS). To quote from the link:
"The software provided with an MSDN Subscription is for design, development, testing, and demonstration of applications in a non-production environment.
The software provided with TechNet Plus subscriptions is for evaluation purposes only."
