Be careful about "will never use more than 16" :-) In the future, home
users may wish to give each family member a couple of /64s to carry
around with them as their personal networks (PANs).
There are plenty of /48s. Address conservation is not an issue with
IPv6 (although address hierarchy is). xDSL and FTTH customers will
get their /48 from an ISP. When that ISP has used up its /32, it can
get another address block from the RIR.
Companies and universities are another thing. Usually, they are not
ISPs. However, if they provide xDSL, fiber or whatever connections to
their employees or students, they _are_ ISPs and should have address
space to use for that.
If they are not ISPs, why would they assign a prefix to their employees
or students? Maybe in the short term, when that's the only way to get
IPv6 connectivity. But after that? For a VPN? I suppose a single /64
should be enough for that.
