You probably want to use OpenVPN or similar to make it so that you have a
static IP address wherever you go, which is routed over the public network.
For example, I have an OpenVPN server which is always reachable, and does
NAT for my machine.  When I connect at a new location, OpenVPN re-starts
and then routes all my traffic over that VPN.

As long as my SSH sessions are idle, I can easily move from one place to
another without losing those sessions.  If data is sent over that
connection, it will die if I'm away for longer than the TCP timeout.  SSH
sessions to random hosts tend to stay up, at least when going from the
coffee shop to the house, etc...
