Google, IBM to fund 'cloud computing' data centers for open research

So says this article in news.com. Clearly, IBM and Google have agreed to divide the Microsoft universe between them -- IBM wants to own B2B, and Google wants to own B2C. We'll see whether Microsoft acquiesces to this plan

I'll be very curious to see if Kevin Burton was right about the open-source release of GFS, MapReduce, and BigTable. If he was, I'm never playing poker with him :-)

Questions:
* Is this just an open service, or open-source software?
* Is it separate storage and processing (like S3 and EC2) or linked processing and storage?
* Does it include advanced functionality (BigTable) or just lower-level components (MapReduce)

Looking forward to finding out more...
