MMGenLive can now install itself on your hard drive, freeing you from having to run it from the USB stick. Users of the latest boot image (v0.0.7) can use the new functionality by running 'mmlive-upgrade' and then 'mmlive-node-setup -d' to begin the automated installation.
Running without the USB stick reduces energy consumption considerably. My Mini-PC node, connected and relaying transactions, now uses only 6.6W.
For more information on running a Bitcoin full node with MMGenLive, see the MMGenLive project page and my Mini-PC writeup on bitcointalk.
