Well, do you have a active/passive asterisk cluster, right? There's no
problem to use DRDB/Rsync/Whatever in this solution. The
"unidirectional" issue is bad for active/active clusters.

I don't see a (really good) reason to use DUNDi in your scenario...
maybe share cpu power for meetme or share zap channels...
