I strongly disagree -- you really want to be able to do as high a
bandwidth as possible. You might think we don't need one time pads
ever anymore, but they are still the one and only provably absolutely
secure method out there -- thus, sources of large numbers of random
bits are going to be of use.

Bad idea. If I hooked it up to my workstation, I'd end up spending
lots of CPU on the thing and possibly get nasty problems with buffers
filling. Not everything on earth is a PC that will ignore the
interrupts if the port isn't in use, you know.
