The big trick here is to figure out where changes can apply. If there is one 
master server that controls what should happen one could easily drop relevant 
files in a cvs repository or something. Alternatively, write scripts that read 
the configuration from a shared database.

It will be more tricky if changes can occur at multiple sites. There is a 
partial description of BGP usage for telephony routing (TRIP) but its only 
about routing, not about applications, so for a cooperating set of asterisk-
boxes it will be insufficient.

Yes please. Ofcourse much of this also has to do with the way your telco 
delivers the E1 lines.
