[Dnsmasq-discuss] Two routers, two dnsmasq instances, can they sync?

[Arseniy Skvortsov]

I was going to implement this a year ago, but unfortunately stuck in  
establishing IP connectivity between the subnets.
Providing you have IP connectivity (VPN I assume), you can pull lease file  
 from one router to another, convert it to 'hosts' file (don't forget to  
compare lease times in case if one of the clients can fly from one router  
to another quickly :) ) and send SIGHUP to dnsmasq instance for it to  
reread new 'hosts'. Path to the file may be passed as --addn-hosts.

If you wish, I can help with setting things up. Maybe I'll be able to  
finish changes in my subnets after.

Either way, would like to see your success (or fail) story here.
