Gotta agree with the other comments on the business side of this decision. You don't want to get caught "faking it" by Microsuck - you think you're in trouble now! Not to make it worse, but if you "fake it" you only give the open-source community a bad name and ammo to the enemy. Your and our integrity are (to some degree) on the line. Check the contract - they're the Skulls, and your that wussy kid Josh Something from Dawson's Creek, but you can beat them if you have an out on paper. If they didn't specify which platform, server, etc to use, you're in the sweet spot. Let them know you'll port your stuff over, but for a fee. That's the one great part of this deal - you might be able to stick it to Redmond one more time. Sweet!
