Simon, This is never going to get high enough up my todo list to try, but I did wonder if a simple "clustered" system could be built using DBUS or similar events. When a lease is allocated DBUS (and a script) is run notifying about that. A little daemon could then use this hook to notify another instance of dnsmasq. In fact I think the hook is run synchronously? So it should be possible to ship new leases across to the other instance
I can think of a number of ways this can be racy... However, for a little home lab it would surely be good enough. I'm not sure how to handle failover, but a few simple ideas spring to mind (I'm thinking of a pure warm standby kind of setup, where something promotes the secondary to primary) Anyway, just shooting the breeze...
