GSM, at least in the Netherlands, uses the priciple that if you're out
of your 'region', that you pay the transit between the home-country and the
place you are. E.g. if a Dutch subscriber is in France and receives a call
from the Netherlands, then the caller pays mobile phone rates for a Dutch
mobile call, and the GSM owner pays a rate from the Netherlands to France,
i.e. the GSM owner pays for its mobility and the extra transit involved.

We could do the same with IP (encapsulating it), but somehow I feel that
this approach will never be popular, either with GSM or with IP...
