AFAICT, this won't let people run existing 32 bit apps out of the box. Instead, it enables the creation of 32 bit stub libraries that can call their 64 bit counterparts in behalf of the application. Although it's possible in theory to run existing 32 bit apps by creating stub libraries for 32 bit APIs, it's likely to require so much effort that I doubt this is going to happen.
