Drahtwerk has announced iScreen 2.0 (http://macte.ch/uF8Jp), an update to the monitor productivity tool for Mac OS X. It adds support for OS X 10.7 Lion and previous generation PowerPC Macs.

iScreen turns any iOS device into an additional monitor that can be used wirelessly with any Mac setup. It combines TCP & UDP networking protocols and a dynamic video compression algorithm that adjusts its content based compression. Version 2.0 also sports improved performance, multi-touch scrolling, a built-in online FAQ and more.

iScreen requires iOS 3.2 or later, a computer connected to the same network as the iPhone and the installation of the desktop drivers

iScreen 2.0 is available on the AppleApp Store in the Utilities category. To celebrate the release of iScreen 2.0, the price has been set to US$4.99 for a limited time.
