entropy gathering (was Re: Why does reading from /dev/urandom deplete entropy so much?)

[Jeff Garzik <jeff@garzik.org>]

As an aside...

Speaking as the maintainer rng-tools, which is the home of the hardware 
RNG entropy gathering daemon...

I wish somebody (not me) would take rngd and several other projects, and 
combine them into a single actively maintained "entropy gathering" package.

IMO entropy gathering has been a long-standing need for headless network 
servers (and now virtual machines).

In addition to rngd for hardware RNGs, I've been daemons out there that 
gather from audio and video sources (generally open wires/channels with 
nothing plugged in), thermal sources, etc.  There is a lot of entropy 
that could be gathered via userland, if you think creatively.
