Right now, we might say "wow, 256 subnets for a single end-user... hogwash!" and in years to come, "wow, only 256 subnets... what were we thinking!?"
Well, what's the likelihood of the "only 256 subnets" problem?
There's a tendency to move away from (simulated) shared media networks. "One host per subnet" might become the norm.
Or possibly maybe Peter M. Gleitz's and Steven M. Bellovin's idea of "Transient Addressing for Related Processes: Improved Firewalling by Using IPV6 and Multiple Addresses per Host" http://www.cs.columbia.edu/~smb/papers/tarp/tarp.html A /64 per host is probably not necessary, however if an end-site has a /48, that's 65K hosts so it wouldn't likely be much of a problem for most sites ... certainly not my house currently or in the forseeable future or my current employer, or most employers I've worked for in the past. -- "Sheep are slow and tasty, and therefore must remain constantly alert." - Bruce Schneier, "Beyond Fear"
