This is one way of doing it. The other way being to exchange live
routing/registration data, and keep and process it locally, somewhat
like what a BGP router does.

It's not the goal here. I'm not looking for "five nines". I'm looking
for a way to :
- connect several tens of E1 channels (thus I need a quite a few
  different boxes) 
- support the fact that any single box may be down. I could drop the
  channels it currently processes, which is OK. But when the user
  dials again, it should work. It should be fairly OK with the client
  performing a new DNS lookup before it registers, if the DNS is aware
  of which box is up.
