I agree that the address space savings is valuable.
The biggest problem we seem to be facing is a large (15000)
population of users/ casual administrators who don't have the 
understanding to set masks according to specifications or 
to reserve subnet broadcast addresses/ subnet 0 addresses 
(ie. not give them out as node numbers.)

Perhaps the best solution is to depend on the router for all
subnetting and arping, and set every host at class b mask.

But there still seems to be some problem with yellow pages,
greping for subnets and having to explain the scheme to 
our users.  A modest cost for efficiency, I hope.
