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
All mdns traffic would be contained on local networking (no routing
Problems where not related just to the network topology but mainly to buggy
implementation, having avahi/mdns/zeroconf/jmDNS based stuff is usually a pain
Some years ago they were mostly abandoned software, i suspect the situation is
not better now...
I definitely would not invest my time on that technology
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.
If we plan to implement something about service discovery it should be
decoupled from lower network layer as much as possible, service discovery is
about applications and should reside in application layer too
Past experiment pushing application layer stuff into networking layer has
failed, moreover this would force to use a specific switching/routing
technology that is not a good idea.
As an example ebrain  that is an "application sharing" software started
some years ago depending on OLSR, then OLSR changed in an incompatible way,
hopefully they soon realized that it wasn't a good idea to depend on a specific
