I think everyone missed the most obvious reason this would be ported.
To give windows users the same level of reasons to buy an ipod as a mac user. Sure, they have itunes, and itunes works with airport express from a Windows computer.
What happens when apple upgrades their airport product to include video, so that you can be running Front Row on your television which is wirelessly connected to your computer in the office downstairs. Steve Jobs said that he didn't think computers belonged in the living room......
I don't think all of ilife will be ported, but I do think that all of the applications needed to run Front Row will be. More importantly, they will be sold WITH HARDWARE, the upgraded airport express which has video output, and an IR port for the remote.
Windows users generally won't buy software that they can get elsewhere cheaper, but if that software comes bundled with hardware, such as the ipod with itunes, I think there may be a win-win scenario for both opinions. Apple sells both hardware in the form of airport express and the IR remote and bundles it with all of the digital life applications including Front Row.
Not only will they get a killer solution, but they will beat those nasty Windows pirates as well if you need the hardware to use the software!!!
Should Apple Port the iLife Suite?
