Sun on the market?

An article in the Seatle Times speculates that Sun's price surge on Friday was predicated on their being open to acquisition.

The paper speculated that IBM, HP, and Dell may be the suitors.

My question is: Will IBM buy them in order to (among other things) take Java to where they want it to go? It's a possibility, and might be the one thing that could prevent Microsoft's .NET from taking over the Java space.
