Mobility is usually done per host, thus you route the /128 over a tunnel to somewhere else and do ND proxying. One doesn't need loads of addres space for this.

The /56 is really intended for 'the mom and pop home', they don't do neato things like multihoming, they most likely don't have an idea what IP is in the first place, and they shouldn't have to either ;) Greets, Jeroen
