    In Mac OS you can add "desktops", which you can conveniently swipe between, which allows you to keep more open/running/to hand, without cluttering the active screen.

    Is it possible (and if not, why not?) to Airplay mirror a particular "desktop", whether or not it's active in the foreground? If so, this would allow you to work on one desktop and run a passive info-only screen (e.g. stock market prices/news) relayed to a TV, all from one computer.

    Hopefully this is possible?

    I believe that the point of airplay mirroring is to mirror the monitor in its entirety rather than a secondary desktop or application, so don't think this is possible. Apple have probably decided on this as airplay does have a slight lag, given it is processed, transferred over wifi then played back like a streaming video. As such, it is designed more for presentations.

    With the iPad and using apps such as Keynote it is possible to have a presentation mode which displays different content on the ipad to the airplay receiver, so i would imagine the only way to do it would be to use a application which supports this.

    It's not possible. Mirroring is mirroring. But, you can set "Displays have separate Spaces" in System Preferences > Mission Control (in fact that should be enabled by default) so you can leave that Space up on the external, without affecting or being affected by what you're doing on the primary display.
