"Startups may keep and continue to use, for development and testing purposes, all the software they received as part of their BizSpark MSDN Subscription. In other words, they have perpetual development and test rights to that software."
"The BizSpark Graduation Offer allows BizSpark startups to keep, at no charge, all the software they acquired through the BizSpark program"
"Under the graduation offer, the MSDN Ultimate licenses that came with BizSpark are perpetual, so startups keep all the tools and platform software they got from the program for development and testing purposes, including Visual Studio and Expression"
"Similarly, startups will also have perpetual rights to all of their Windows and SQL Server production licenses"
Now your claim may be that BizSpark doesn't supply enough licenses for you, but it is FREE. After BizSpark is done, you never have to pay MS a cent to keep and use the SW acquired in BizSpark.
In fact, I didn't realize they'd waived the $100 fee.
Like I said, if you want to upgrade or get additional licenses, you have to pay for those. You can build your $50B empire all on BizSpark, although you'll just have to write a very efficient backend to handle the transactions with only a couple of SQL instances, but there is nothing stopping you, but your ingenuity :-)
