There are two situations when the hypothetical main servers go offline.  Either
you want the remaining clients to connect to each other, or you want to
introduce new server nodes that the clients can connect to.  I think the first
case is better solved by tinc having an option to automatically make outgoing
connections as necessary, instead of just using the ConnectTo statements.  The
second case has the problem that the clients do not know the public key of the
new server node.
