I'm using an Araneus Alea I, from http://www.araneus.fi/products-alea-eng.html.  I'm sure others would work as well.  I know the creator of this device personally though, so it's the one sticking out of the back of the box I own.  :)

As for the daemon, well, I may have to find the time to clean it up.  :)

Basically, I map the USB dongle into one VM I use for "control stuff" that doesn't run anything else, and is running a scaled down NetBSD install under VMWare.  The daemon accepts connections over TCP, and sends chunks of randomness to whoever asks, as much as they request, when it is available.

The receiver then encrypts the data with a 128-bit key to scramble it further, and feeds it into the system's random pool.  From there on, /dev/random just works.  It basically attempts to keep the random pool full, so while /dev/random may block, it won't do so for very long.  I believe the daemon checks once every 100ms or so.
