Google bashing...
Just scanned the posts, and I tend to agree with the thought that this won't be included in Office - way too much scope for backlash. I can't imagine a European bank/qango/govt. service/police force etc risking running foul of any DP laws, and the whole OpenDoc/OpenXML flap indicates MS will do pretty much anything to keep Govt contracts.
I don't buy the ad-ware bashing theory either. MS may talk that talk, but they want us to buy their anti-crapware crapware, they don't want to pay lawyers to clog up the courts - no proft for them (I don't think MS count 'goodwill' as proft).
I reckon that this is a move in the Google war, and probably aimed more at grabbing share-holders attention than developing product. That and sniffing around at the advertising market. This smells a lot like pre-FUD dis-information to me: "Hey, we're gonna take 'Adwords' out with our patent portfolio - better talk to us before Google go bust...", or similar.
