* Wireless

Those three I see a lot at various people's places.

Also note that you should stop thinking of "today", think about what
might be possible in 10, 20, 30, 40, 50 years...

You don't have to bother your customers and your customers don't have to
bother you anymore.

The /48 for end-users might indeed be a bit on the much side, but a /56
is IMHO perfect fit for any home-site. The huge advantage of just giving
out /48s though is that you don't have to care about if the connection
is terminated at a home or a big corporation, as they say with shirts:
one size fits all, simply as it is way too big.
