A character device load balancer that can do random or round-robin so I can replace /dev/random and /dev/urandom with a load balanced character device that feeds random numbers of bits from random random number generators in random amounts mostly as a matter of cargo-culting and so that encryption programs have no idea where their entropy is coming from. This can be done in the application but that is what I want to avoid. I am certain this will never exist as I am very likely the only person on earth that wants this.
