Re: IPSEC tunnels and Mobile IP
I would disagree on the point about not needing mobile IP in a hotel room.
There is a good reason why a hotel should offer support for visiting
laptop, $$$. Hotels are already providing enhanced office services to
their customers for a fee. Offering Mobile IP would allow them to provide
enhanced network access (above dial-up modem speeds) to business meeting
attendees, conference gatherings in adition to guests.
The only way Mobile IP will get out of the lab and into commercial products
and service offerings is by allowing service providers the ability to
generate revenues necessitating scaleable, robust authentication and access
control for billing purposes.
