MSFT and Adobe

Well, jeeze, this is going to get interesting, isn't it?

I'm looking forward to hearing more details on "Microsoft is expected to show a new friendliness to the open-source community by unveiling plans to release the source code to a part of its Silverlight technology at MIX 07 next week, according to sources familiar with the company's plans."

Will this be shared source or open source - like with non-MSFT committers and what not?

Update: So I read through a bunch of stuff and I still don't quite "get it". Multi-platform means Winders and OS X? Em, I thought MSFT sold Linux now? No Linux? But Flex runs on Winders, Linux, Solaris, and OS X? Also, didn't find any details on the OSS details - anyone see any?
