Imagine a scenario, where every participant brought a Laptop to a meeting and watched your presentation on that Laptop's display - participants would probably sit on a table facing each other, instead of the wall.
No adjustments were necessary; images would be scaled automatically on arrival, to best match the receiver's display-capability. To support lively meetings, everyone participating could, with a single button click, turn his computer into the presenting device.

Well, it's here!
Meet TiffanyScreens, a presentation tool, able to capture the content of the presenter's screen and send it to multiple computer screens at the same time. Best of all, any computer can seamlessly become the presenting computer, no matter if connected wirelessly or through an Ethernet cable.
An Early Access Release is available as Windows executable, Mac OS X disk image (dmg), and also deployable via Java Webstart.
