I've been thinking about it for development as well, but I now think that resolution isn't as big a concern as I initially thought.

You'd be able to have a virtual desktop of (essentially) unlimited size. You're frontmost task could be high resolution, but ancillary tasks could be lower resolution or high resolution but partially occluded by your field of vision. This wouldn't be opening an IDE to fill the entire screen - it would be a multi-window environment with at most a few primary tasks using up most of the screen real estate. Like Mission Control with real time zooming in a 3D environment and no distinction between workspaces.
