DIY ChromeOS?

rheum101 writes: Fellow slashdotters — I have been considering the pros and cons of the recently announced Google ChromeOS. I would love to have a bog standard PC boot fast (10 secs), load straight to browser for all my Gmailing and day to day surfing (and then maybe give me a "load Windows" button if I want to pull in all my legacy thick apps). Even better would be to have this on a USB stick so that ANY USB bootable PC can get me to my online apps ASAP. Imagine how frustrated that I am to have to wait for another year for ChromeOS and to have to buy a ChromeOS — specific machine. But wait! All of the pieces I need to do this are here in the OSS world today — I am just asking for a very fast loading Linux+Firefox on a USB stick, right? Maybe the touted 10 secs Ubuntu boot or the DamnSmallLinux can do the trick somehow. Can anyone help me get this pulled together? (I am not a source coder, but can handle drive partitioning and such)......
