I'm not interested in alternative OS's (yet), mostly because I want the device to be as finger-friendly as possible for my car. I'm sure I'll try some of the other installs within a few months though.

I decided to try to hack the demo vkb to make a transparent window yesterday, but failed and quickly found a thread that pointed out that transparency only works with desktop plugins. I might try stealing screenshot code and throwing that underneath just as a test, but I can't imagine I'll be getting very far with any of these ideas
