Yuckk! Why put all the intelligence in the central system. Look at the 
Internet, dumb routers and packet switches flipping data bits all over 
the place with all the intelligence in the hosts at the periphery. Paul 
has a mail server at that receives his mail and if he 
really needed access remotely, he can just run a POP server there and 
pick it up anywhere there is a net connection. Or if he cares about where 
the mail lands, he can have forward all his mail via UUCP 
and then poll via TCP/IP or modem from wherever he happens to be located.

IPv6 will save us all. We can address each cell in our bodies and have 
enough addresses left over for the light switches. Every child will 
receive their IPv6 allocation at birth.
