Is there any notion of a standardized&#xA;&gt;&gt;&gt; invoice serialisation? If i pay for two Burgers and one Club Mate, how&#xA;&gt;&gt;&gt; would my Bitcoin Wallet be able to know that?&#xA;&gt;&gt;&#xA;&gt;&gt;&#xA;&gt;&gt; No. There are XML-based (shudder) standards for electronic invoicing that&#xA;&gt;&gt; include all sorts of bells and whistles; the PaymentDetails message could&#xA;&gt;&gt; easily encapsulate one of them in an &#39;invoice&#39; field extension. Or we could&#xA;&gt;&gt; reinvent the wheel and come up with our own, but I&#39;d rather use an existing&#xA;&gt;&gt; standard (or maybe a subset of an existing standard).&#xA;&gt;&gt;&#xA;&gt;&gt; I didn&#39;t want to wade into that swamp for the 1.0 version of the payment&#xA;&gt;&gt; protocol.&#xA;&gt;&gt;&#xA;&gt;&gt;&#xA;&gt;&gt;&gt; Right now, i would simply&#xA;&gt;&gt;&gt; put that into &#34;memo&#34; and come up with my own serialisation mechanism.&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&#xA;&gt;&gt; &#34;Two Burgers, one Club Mate&#34; seems pretty user-friendly.&#xA;&gt;&gt;&#xA;&gt;&gt;  Second, is there a way to communicate acceptance levels of TX&#xA;&gt;&gt;&gt; (unconfirmed, 1 conf, 6 conf) maybe using several PaymentACK?&#xA;&gt;&gt;&gt;&#xA;&gt;&gt;&#xA;&gt;&gt; No, because the Payment-&gt;PaymentACK communication round-trip is done in&#xA;&gt;&gt; one, non-persistent http request-response round-trip.&#xA;&gt;&gt;&#xA;&gt;&gt; I don&#39;t think we want to allow merchants to push messages to the wallet&#xA;&gt;&gt; (wouldn&#39;t take long for merchants to use the opportunity to push annoying&#xA;&gt;&gt; advertising at me, I think), and I don&#39;t think we want wallets to poll the&#xA;&gt;&gt; merchant. Although maybe a payment protocol version 2.0 feature could be a&#xA;&gt;&gt; PaymentACK extension that says &#34;ask me how the transaction is going at THIS&#xA;&gt;&gt; URL in THIS many minutes.&#34;&#xA;&gt;&gt;&#xA;&gt;&gt; --&#xA;&gt;&gt; --&#xA;&gt;&gt; Gavin Andresen&#xA;&gt;&gt;&#xA;&gt;&gt;&#xA;&gt;&gt; ------------------------------------------------------------------------------&#xA;&gt;&gt; Introducing Performance Central, a new site from SourceForge and&#xA;&gt;&gt; AppDynamics.
