I'm reminded of somebody saying, "they'll never need more than 640k". :-/

But anyhoot, 16/48 bit majors/minors seems reasonable to me.
Of course, this is a blind guess - we really should discuss how
majors/minors will be assigned and used first. We could easily gobble up
128-bits with a poor system, or, improve the current one and stick with
16-bits.
