Okay, now this is a great idea: create a series of hands-on labs for people to use to get familiar with your product offerings, with a special focus on upcoming versions and new, cool functionality. Like, oh, say, Exchange 2007.
Even better: put it online for free, with both 30 minute or 90 minute versions. Make it so all the users have to do is have a Windows Live! (Passport) account and be willing to register.
Best yet: Let users take any lab from TechNet or MSDN, submit a completed evaluation, and then give away an Xbox 360.
That's just cool, and a great step for promoting training and certification.
