MAC addresses are 48 bits. There are 65,536 times as many MAC addresses
as there are IPv4 addresses, so today there are around 32,768 MAC
addresses per human on the planet.

If you still don't like this... just have a button on usb.org that
returns a monotonic counter of, say, 64 bits. Now if 10 people get an ID
number every *second*, you'll run out in 58 *billion years*!

Oh, and you don't even have to pay thousands in software development
cost. Just go download a free website hit counter :) With so many
trivially easy ways to do this, I can't attribute their failure to
anything but greed. It's pretty sad when people pay thousands of dollars
for... a number.
