Generating Unique Keys

Unique over what domain?  For all time?  For just this run?  For just this
computer?  Int, float, string?

I'll just toss something simple out there to stimulate your creative juices.
What about:

    "%s:%f:%f" % (socket.gethostname(), time.time(), random.random())

I realize it's not guaranteed to be completely unique, but for most uses it
will probably be "good enough".  In fact

    "%s:%f" % (socket.gethostname(), time.time())

will probably be "good enough" on systems with decent clocks:

    >>> time.time() == time.time()
    False
