I have not had time to look at LIM, so this may be a stupid comment...

IMHO: This kind of makes some of the enforcer pointless if an external mgmt. app is doing the key rollover (even more so in v2 ????). I would imagine that most operators would prefer a active-active system where the two enforcers communicate state to each other and both signers act as masters for the zones. I do realise that this might be a lot more work :)

Out of interest, has there been any architecture discussion for this kind of functionality? I could not find it...
