thanks for your reply - yeap, I'm aware your approach and I'm sure, that we'll have some chat next time I visit Luebeck.
Anyway, I'm not convinced that a single broadcast-domain spawned by batman-adv is going to scale well compared to a routed setup, but you can still prove me wrong ;-)
However, the discussion of freifunk network architectures (full bridging vs dynamic bridging) is off topic on a tinc mailinglist, so we better stop now ;-) - fup2 freifunk-bonn at lists.bonn.freifunk.net
