at Ninux we have the same setup. Some nodes of the OLSR network have a
VPN interface done with tinc-vpn. We used as last resort if some links
fail, like an OOB access.

in the VPN subnet, OLSR see a full mesh of connections among the vpn nodes

to prefer wireless links instead of VPN we used LinkQualityMult
configured with 0.2

I dont understand what feature the plugin adds. I cannot achieve the
same thing configuring olsrd.conf in the VPN nodes with the required
LinkQualityMult ?

thanks for clarification
