maybe we can use ROT26 :D

DNS is not meant to transport arbitrary data, you have many
restriction that you will quicly hit (63 octets per label, 255 total)
The 2 advantages of DNS are pseudo anonymity (the LEDE team will not
have the IPs of the routers) and firewall "bypass"
The disavantage is that you can't know how many routers, if someone
tries to mess with you metric, ...

I would prefer to start a real telemetry service, sending lots of info
(a unique id/board/revision/allpackages versions/...) in an extensible
format (json?)
put that behind an nginx with agressive rate limiting, drop the IP
information, and maybe make this data public

Haven't looked how debian and others are doing telemetry
