Collecting entropy in headless systems

[Roy M. Silvernail]

Windows sucks.  (but you knew that already)  It has no /dev/random or
/dev/urandom, and I'm faced with a need to collect some good-quality
entropy for a crypto app.  Adding to the merriment, the systems involved
will be semi-headless and are unlikely to have a hardware RNG.  (e.g.
though they may have rodentia and keyboards, neither is likely to be in
use, and I can't require a HWRNG)  All the entropy collectors I've seen
mentioned for Windows (and there aren't many... EGADS seems to be the
leading contender) use keyboard timing and mouse position as primary
sources.

I just need enough to seed a PRNG, but I also can't wait around forever to
collect it.  What's a cpunk to do?  (sorry, migrating to *nix isn't viable
in this case)
