Microsoft vs. TestDriven.Net Express
Jamie Cansdale has just published the email corrspondance between him and Microsoft about TestDriven.Net on the Express SKU. Among other things, this has led to him losing him MVP status, pulling the TD.Net express, and more than a bit of angst. The clause that they are using is: "You may not work around any technical limitations in the software."
I strongly suggest reading the entire set of emails, and considerring that the clause they choose to use, that includes everything that they don't like, from key shortcuts to VS Macros.
