On the hardware side, it cannot be done because the processor is not designed to do this. The processor knows where it's memory location is and that is all it will use. As for virtual memory, I've never thought about this for a phone but I don't see anyone coding this for windows mobile. Is there really a need? The device you buy is designed to operate a specific OS and it does it well (most of them anyway). It's not until you start tinkering with things that you run into mem issues. Besides that, looking at the stats on the new hardware available for the mobile platform in the next year, I don't see us having many issues with lag anymore. 1.5 dual core processors, separate GPU's and devices showing 1+ gigs of RAM. I think overall that we will be okay without virtual memory.

EDIT: Also, people would really screw up their phone when they pop their SD card out before powering down the device or using Disk Drive mode when connecting to PC.
