Yes, that's what I was imagining (literally spawning new monitors in the viewspace) but this simply isn't that. Also with Oculus you need to have the physical monitors to support it (for now):
>The latest version (0.9.5) now supports multiple monitors as long as they are connected to the same GPU as the Rift. i'm working on adding support for multi-GPU and Optimus configurations. Multi-Monitor is only available in curved mode at the moment but I'll add support for flat mode at some point too.
In theory you can add N number of monitors to your desk and simply look at each one. Being able to simple turn your head and hook is a huge win over multiple, virtual desktop spaces (otherwise why would you buy an additional monitor?).
So a dynamic way of adding and removing monitors form your setup. Too bad this one doesn't quite work that way and wouldn't work as well (especially with, as you said, a huge clunky device strapped to your face).
