(with apologies for the embarassing levels of ignorance this likely displays)
Could other applications read your auxiliary vector, and hence the seed you're using? Would this then have much effect on the guessability of subsequent random numbers?

I don't think that's a real problem. The random bytes are not available to outside applications (unless they trace it like debuggers or strace do, but in this case, it would be easier to just read the random seed or just overwrite the seed).
