By the way, for those of you that are interested in testing the Nexus 7 you can easily follow the instructions on https://wiki.ubuntu.com/Nexus7/Installation to get Ubuntu set up. However, this makes the Nexus 7 a unitasker devoted to testing Ubuntu. A better plan is to follow these instructions: http://forum.xda-developers.com/showthread.php?t=2011403 to set up multiple ROMS on the Nexus. This way you can use it both as an Android and as a Linux ARM testing platform.
Either way you decide to go, once you have Ubuntu set up, install java-6-openjdk-armhf and you will be able to start testing Ignition clients. Oracle has a JDK for the A7 ARM however it does not contain the javaws web start file. If anyone can compile one I would be interested in testing it as I am sure it will be faster than the open version.
