IMHO something really fishy's going on there. If I explicitely write data into the pool, it shouldd not stay at "zero", from wwhat I understood about how /dev/*random work.

I'm mainly wondering why writing stuff to /dev/*random does not change the entropy from zero to at least any low non-zero value...
I ran into this the other day myself and when I investigated the kernel code, I found that writes to /dev/random do accept the data into the entropy pool, but do NOT update the entropy estimate. In order to do that, you have to use a root only ioctl to add the data and update the estimate. I am not sure why this is, or if there is a tool already written somewhere to use this ioctl, maybe someone else can comment?
