Bit 1: I've recently stumbled upon Microsoft Empower for ISV program. Now, that's a deal - if you are an ISV developing for Microsoft technologies (or commit to deliver such a solution in 2 years) then for $400 per year you can get one MSDN Premium Subscription and for user licenses, up to five licenses to Vista, XP, Office 2003/2007, one server and up to for CALs to servers. The goodness lasts for up to 2 years. I wonder, what's the catch?
