Yesterday, we (Marek, Julian, Linus) had some thoughts about the advantages of having a multicast-aware BATMAN-Adv. Also some first ideas about the actual implementation in BATMAN-Adv, which is not a trivial task, have been discussed. The results so far and the irc-log can be found in our wiki from the Lübeck-Freifunk (http://luebeck.freifunk.net) in the section Network->BATMAN-Adv-Multicast-Development. We definetly want to push this feature further as it is especially very useful in Mesh-networks and would like to hear from any other ideas of how to implement this in the most efficient way and if there are any concerns about the ideas for implementation yet. Also a trac-enhancement-ticket can be found here: http://www.open-mesh.net/ticket/128
Sincerely, Julian, Linus - MetaMeute
