        [Tim McCarthy]  But if it's guaranteed to be globally unique
then it must be predictable and therefore unsuitable. Buck, thanks for
the suggestion but I'm really looking for something that would develop
the seed for random number generation rather than the number generation
itself (the crypto-geeks get all bent out of shape when you use pseudo
random number generators without at least providing a seed that was
generated from machine noise or random mouse movements). I just thought
there might be a (hidden) function that could capture something like
random memory values over a period and provide that as input.
