Heya,
Just a quick note to say that I’ve now put together an Electrum (Bitcoin Client) live CD based on Ubuntu 12 LTS. You’ll also find Armory and Bitcoind on it too.
For now I’d call it ‘alpha’ but it should be stable enough since it has only a few modified components:
Download the ISO here: coinos.iso
MD5 Sum: b17f492db98ff57801891dfe8302b1c8
DISCLAIMER: While this CD should do nothing more than boot into a Desktop environment it has tools on it (like basically any Linux) that could destroy data if not used correctly. I take no responsibility for your success or failure but suffice to say ‘it works for me’.
Enjoy!
