Why not reuse that for dynamic address lookup? Just a few&#xA;&gt; changes are necessary to enable complete user at server.com handling:&#xA;&gt; - Extend the protocol so that &#34;reply&#34; messages can be signed by a fixed&#xA;&gt;  public key&#xA;&gt; - Extend &#34;checkorder&#34; messages so they can specify an account to&#xA;&gt;  send BTC to. Or standardize on how to put the account into the&#xA;&gt;  message field.&#xA;&gt; - Enable DNS lookups for IP transactions. The DNS-only proposals could&#xA;&gt;  also be used here to avoid having to use the IP transaction protocol&#xA;&gt;  sometimes. The public key for signing &#34;reply&#34; messages can be gotten&#xA;&gt;  from TXT records. This will be safe with DNSSEC and Namecoin. With&#xA;&gt;  plain DNS Bitcoin could take a SSH-like approach and ask the user to&#xA;&gt;  verify the public key the first time it is used, remembering it later.&#xA;&gt;&#xA;&gt; DoS attacks are already handled by the IP transactions code: the same IP&#xA;&gt; address is always given the same bitcoin address until it pays to that&#xA;&gt; bitcoin address.&#xA;&gt;&#xA;&gt;&#xA;-------------- next part --------------&#xA;An HTML attachment was scrubbed...&#xA;URL: &lt;http://lists.linuxfoundation.org/pipermail/bitcoin-dev/attachments/20111216/f86f05de/attachment.html&gt;</html></oembed>
