Good idea.

Also, the Rasberry PI includes a hardware random number generator
and, as far as I can tell the Dreamplug does not. High-grade random
numbers are essential for most crypto, and therefore for security, and
they are quite difficult to do with software, especially on a headless
server with solid state storage.

For that reason alone, I would say the Rasberry Pi is a /far better/
platform for the Box than Dreamplug.

I have written software intended to solve this problem for the
Dreamplug and other systems without a hardware RNG

There are also several other ways to solve it; see the paper
on that site for discussion. Personally, though, I'd be extremely
reluctant to use any system without a hardware RNG for
security-critical applications.

The only way I know to get a hardware RNG on a Dreamplug
would involve getting Turbid into Debian:

That lets you use the sound hardware on the plug as an
RNG. This looks problematic since some users would
want sound for other applications.
