Why not reuse that for dynamic address lookup? Just a few\n\u003e changes are necessary to enable complete user at server.com handling:\n\u003e - Extend the protocol so that \"reply\" messages can be signed by a fixed\n\u003e  public key\n\u003e - Extend \"checkorder\" messages so they can specify an account to\n\u003e  send BTC to. Or standardize on how to put the account into the\n\u003e  message field.\n\u003e - Enable DNS lookups for IP transactions. The DNS-only proposals could\n\u003e  also be used here to avoid having to use the IP transaction protocol\n\u003e  sometimes. The public key for signing \"reply\" messages can be gotten\n\u003e  from TXT records. This will be safe with DNSSEC and Namecoin. With\n\u003e  plain DNS Bitcoin could take a SSH-like approach and ask the user to\n\u003e  verify the public key the first time it is used, remembering it later.\n\u003e\n\u003e DoS attacks are already handled by the IP transactions code: the same IP\n\u003e address is always given the same bitcoin address until it pays to that\n\u003e bitcoin address.\n\u003e\n\u003e\n-------------- next part --------------\nAn HTML attachment was scrubbed...\nURL: \u003chttp://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20111216/f86f05de/attachment.html\u003e"}
