Ok... I see that you had a bad time using it.
I think it may have been because of how multicast ip packages work in
mesh networks... and that is why i'm proposing to have local mdns cache
servers, that proactively trigger mdns requests to their networks
(locally), and share that information with the rest of the mdns caches
via Alfred.
All mdns traffic would be contained on local networking (no routing
involved).
in libremesh, the "local network of each node " is actually the whole town (or
neighborhood). batman-adv creates this extended layer2.
so only option would be to keep the mdns cache confined to the localhost (the router) and
only use it to announce services located on the router.
you could make a webinterface on the router for the user to manually setup extra
announcements, for example a homeserver
(commotion firmware had this)
but at that point, you're basically not using avahi for anything anymore ;)
NicoEchaniz told me that there where some issues with mdns in the past,
but I guess this approach was reasonable... What do you think?
It would be very useful if you Gio and Pau could share a little bit
more about what was your experience with this.
Also, you are right Pau... it would only work on a certain layer... and
it would need something to coordinate with bmx6... but as of now, I
feel that this is a good start.

using it for the dhcp leases share system of dnsmasq, but

it would work only for the cloud (not the entire network). So a
kind of
bridge might be implemented.
Would be nice to put some effort here.
I talked ahout this with nico a bit. We've also had a bad experience
with Avahi in general.
Maybe we can do some brainstorming about what we would like to
accomplish and then share ideas on how to do that.
Nico is motivated to work on this and that's awesome :)
Cheers!
Nico
