I'm going to go out on a limb and make a prediction: in the near future, Microsoft and Novell will announce that Microsoft is opening up all or most of .NET and chunks of the Longhorn technologies. This will include submitting Avalon/XAML, Indigo , and the rest of .NET to ECMA as standards. Furthermore, royalty free grants to all relevant Microsoft-owned patents will be issued. Here's my evidence: first, Novell is implementing Avalon and Indigo. They wouldn't be doing this if they didn't have a reasonable expectation of being able to distribute it legally. Second, during the recent GNOME Mono/Java argument cryptic statements like this were made: "The Mono/Java argument is a real mess in this respect – we discussed it some in public, but it turns out all the relevant facts aren't public." What relevant facts are those? A Microsoft patent grant would be very relevant. Third, Microsoft continues to insist that they're not going to be Evil anymore (really, you can trust us this time). But keeping Avalon/XAML proprietary (and trying to proprietize the web) would be _proof_ of Microsofts continued Evilness. And finally, there's this very incriminating photo of Novell's Nat Friedman and Miguel de Icaza participating in a chorus line with Microsoft's CTO. What more proof do you need that some sort of (unholy?) alliance is afoot? You heard it here first, folks.

__More:__ This may only refer to the C#/ECMA patent grant but Miguel has also said this: "As previously reported we (Novell) are working on the legal items
ourselves, and will have an official statement when we are done."
