thank you. nice list, but mostly the details about used techniques are not mentioned. most of the systems are using central servers and have commercial business plans. so that was not the task on this thread.

with *mumble* you can at least install your own server, even on openwrt, and its open source..

but, best app on your list might be the *pttdroid* https://play.google.com/store/apps/details?id=ro.ui.pttdroid

its a very simple app which needs NO server! so within our batman-adv networks its running nice, without any configuration needed :-o

p.s. even when you are alone on your mesh it seems to be a nice app for debugging purposes, because you can create broadcast- and multicast usertraffic very easy..

Has anyone looked into either a piece of hardware or a smarphone app that would allow for functionality similar to CB radios but over a wifi mesh fabric?
