What do you mean by "under some new roots" ? If I believe Netki, there is enough people who want to have a Bitcoin address stored in DNS, for at least one company to thrive. :) All I am proposing is a new usage for these already existing DNS records; not only to receive BTC, but also to sign requests with them. > It still may be worth exploring the compact cert+optimized BIP70 (no > DNSSEC) in a qrcode if making a network that stores small bits of data > really is beyond us :( >=20 Heh, pastebin + base64 encoding the PR could work. However, it might violate their ToS. More seriously, there might be some legal issues for a company willing to provide that kind of service. Re QR codes: 150 bytes, using base43 encoding, is not too bad.
