Let me just put my best Admiral Ackbar impersonation on, here: in the light of the recent patent wars, do I see a patent lawsuit in the future? "We kind of gave them a part of our functionality, but we didn't intend it and they're thus infringing on our patents." Yes, this is patently absurd (pardon the pun), but so are 99% of the patent cases out there; but even should it be brought to court and thrown out, it would be good fertilizer for the one core MS competency: FUD (see the current Android patent craziness).
With this in mind, I fear Redmonders bearing gifts.
