Yeah, the idea is to build a dynamic DNS service, distributed if possible.
I see no point in building a freedombox if its DNS system is based on
"cloudy" (or mainstream if you prefer) services like dyndns.

Well, pay the bill for a DNS domain at least, not that expensive though.
Some are already rented by people around here.
Bandwidth shouldn't be a problem if the system is decentralized. I guess
the best would be for such a system to be able to support multiple domain
name, so that if some fb user wants to own and use one, he/she could
manage it.

Nice, sure I'd like to see/test that. I'm not a lot in redis and all, but
might be usefull in the futur.
