This is an idea that is inspired by the devices that goTenna are selling. Is it possible to create a 'chat system' type of package that will work with OpenWrt's 802.11s mesh network?
Ideally, I would be able to send a message from my smartphone that is connected to an openwrt router. This router will then pass it on to other openwrt routers via the mesh network. Eventually, the message will arrive to someone else's smartphone that is also connected to openwrt router and pop up on it.
I can see a couple disadvantages on this type of set up. The short range of the wifi is not ideal but there are ways to extend this. Many of the routers are not 'pocket-able' but some of them are portable enough. Off-grid and open-source are what I'm after in this idea. I'm not a developer so I wouldn't have the means to make this a reality but I'm curious to hear your thoughts on this.
