show me a single unix system with 100k's of users?

I'm sure there's a few. but not 'hardly useful' if not supporting
less than 100k
also:

$ grep 'uid_t;' /usr/include/sys/types.h
typedef __uint32_t      uid_t;          /* user id */
so like.. 32768 < 100k

which isn't to say unix user/groups etc. is be-all-end-all
of "user systems" -
but it works pretty well for most cases - and this statement
quite simply *not true* - run a workgroup lan for like 5 minutes -
and you'll find that 'hey this quota thing is a good idea'
