I'm a geek, a role-player and a biker.

I work for Diamond Light Source, developing open source scientific software for the UK national synchrotron facility. In the past I have worked in the robotics, mechatronics and laser micro-machining industries.

comment What are the risks of making ether-wake available to all users?
If you wanted to isolate infected machines, wouldn't you just manage this at the network level, shifting them into an isolated network by MAC address, rather than powering them down? Just powering them down wouldn't stop the user pressing the power button on the machine when they got to their desk. Anyway, it sounds like the way to go is to create a database of who is allowed to power on what, and run ether-wake from a wrapper script which only allows a user to remote power up machines that they have personal responsibility for. This would give you the benefits, while mitigating the risks.

comment Are backups of truecrypt volumes with different pass phrases a security risk?
Agreed, by copying the contents of the volume rather than copying the volume itself, you are already taking the hit of decrypting everything and re-encrypting it, so for a (hopefully) write once/never read volume the overhead is probably worth it, compared to having that overhead every time you access any file in a working volume. Also, your working volume can be re-encrypted at any time to make it more secure, it would be much more effort to go back through all of your backups and do the same if a vulnerability is found.

Thanks CodeInChaos, this is useful information, especially the suggestion at the end of the page that each new backup volume should be created with a cascade of cyphers.
