A VPN is, by my definition, any case where one overlays the global Internet
with another private Internet using tunneling. Tunneling procedures today
include MPLS, IPSEC, IP/IP, GRE/IP, and probably several others. The big
difference between doing this and doing the same thing over, say, and ATM,
Frame Relay, or X.25 network is that the latter things are not the
internet. They are virtual circuit switch networks.
MPLS is also a virtual circuit switch network of sorts; the principal
difference between it and Frame Relay is that it runs over an arbitrary
infrastructure. Could virtual circuit switch be supported from a cell
phone? Probably. Is it? No plans that I know of: if you want circuits, they
already support TDM circuits.
You could certainly support an IPSEC VPN, though. This amounts to
encrypting the tunnel back to the Home Agent for the purposes of talking
with other objects that are physically or virtually within the network your
home agent is managing, or participating in other VPNs in the same manner.
