Some of my friends have already worked on 128 bit processors - address 
space, that is.  Not at Intel. Not in academia. In industry, at major 
companies.

Heck, Itanium had an 80 bit address space - what I call a "folded" 
address space.  IMHO the big argument for which is sharing libraries,
at different 64 bit addresses, but at the same address in the unfolded 
80 bit virtual address space.

I vaguely recall a Philips processor with 70 or 72 bit addresses, but 
can't find a reference.  So it may just be a failure of my memory.
