I don't understand what you mean?
The user gets charged and is able to access services (e.g. internet access).
That's the 3gpp model and ISATAP can be just one of those services.

I lost you here. What are the admin domains when the user is at home?

Anyway we seem to have come full circle again.
But please take note that there are people on this list who would like
to stop discussing and start finishing off those specs now pending for
