 This system should be quite scalable. Both qTox and IPFS are based upon distributed hash tables (DHT) so that each peer does not need to store the full index of data for the entire network. Caching or pinning of IPFS data and its content addressability means that if a file or blog becomes popular then performance should improve as the number of downloads increases, which is the opposite of the client/server paradigm.

+** Writing many images quickly
47 
+There may be situations where you need to write the same disk image to multiple drives at the same time in order to maximize rate of deployment. In the instructions given below the *dd* command is used for writing to the target drive, but to write to multiple drives you can use a tool such as [[https://wiki.gnome.org/Apps/MultiWriter][GNOME MultiWriter]].

+For example on Arch/Parabola:

+
51 
+#+begin_src bash
52 
+sudo pacman -S gnome-multi-writer
53 
+#+end_src

 Mesh networks are useful as a quick way to make a fully decentralised communications system which is not connected to or reliant upon the internet. Think festivals, hacker conferences, onboard ships at sea, disaster/war zones, small business internal office communications, protests, remote areas of the world, temporary "digital blackouts", scientific expeditions and off-world space colonies. The down side is that you can't access any internet content. The upside is that you can securely communicate with anyone on the local mesh. No ISPs. No payments or subscriptions beyond the cost of obtaining the hardware. Systems need to be within wifi range of each other for the mesh to be created. It can be an ultra-convenient way to do purely local communications.

 Routers are intended to build network coverage for an area using small and low cost hardware. You can bolt them to walls or leave them on window ledges. They don't have any user interface and their only job is to haul network traffic across the mesh and to enable peers to find each other via running bootstrap nodes for Tox and IPFS. Copy the image to a microSD card and insert it into the router, plug in an Atheros wifi dongle and power on. That should be all you need to do.

 It's better not to trust images downloaded from random places on the interwebs. Chances are that unless you are in the web of trust of the above GPG signatures then they don't mean very much to you. If you actually want something trustworthy then build the images from scratch. It will take some time. Here's how to do it.

 When you first boot from the USB drive the system will create some encryption keys, assign a unique network address to the system and then reboot itself. When that's done you should see a prompt asking for a username. This username just makes it easy for others to initially find you on the mesh and will appear in the list of users.

 On the ordinary internet the date and time of your system would be set automatically via NTP. But this is not the internet and so you will need to manually ensure that your date and time settings are correct. You might need to periodically do this if your clock drifts. It's not essential that the time on your system be highly accurate, but if it drifts too far or goes back to epoch then things could become a little confusing in regard to the order of blog posts.
