this means changing every app to be aware of IP changes so that they know 
that they need to re-connnect to the far end. and for many apps, 
modifying them to be able to pick up where they left off (and to do so in 
a secure way so that bad guys can't claim to be you on a new IP address 
and connect into an authenticated session)

good luck in re-writing the world.

now, if you are willing to throw way all existing software (and solve the 
reconnect security problems) you may be able to make it work, but there 
are no apps that work this way today that I am aware of.
