Seriously. If they cannot give you a static IP address, they're not worth
being a customer of. ISPs need to get that clue.
As for your vpn, you should be able to restart it from the client side when
this happens. For exmple in your ppp-up script or something. If you have
a tunnel up with a subnet behind your machine, eg not using the dynamic IP
from your ISP for tunnel traffic, your applications won't even notice anything
apart from a brief glitch in the matrix.
