Doesn't this describe what Guix already does? If not, how? I don't understand the 'like DNS' part, though, so maybe that's where it differs. Do you mean substitute a different protocol for HTTP? We already use a single TCP connection per server for all narinfo queries, and nars found on one server aren't queried again. Kind regards, T G-R Sent on the go. Excuse or enjoy my brevity.
