The mobile has a key, the desktop has&#xA;a key and a third-party security oracle has a third key.  The oracle&#xA;would have different security thresholds for countersigning the mobile.&#xA;&#xA;This way you can have the same overall wallet on all devices, but&#xA;different security profiles on different keys.&#xA;&#xA;That said, I do agree that mnemonic phrases should be portable, and find&#xA;it unfortunate that the ecosystem is failing to standardize on phrase&#xA;handling.&#xA;&#xA;On 2015-03-11 04:22 PM, Mike Hearn wrote:&#xA;&gt; Users will want to have wallets shared between devices, it&#39;s as simple&#xA;&gt; as that, especially for mobile/desktop wallets. Trying to stop them from&#xA;&gt; doing that by making things gratuitously incompatible isn&#39;t the right&#xA;&gt; approach:  they&#39;ll just find workarounds or wallet apps will learn how&#xA;&gt; to import seeds from other apps. Better to just explain the risks and&#xA;&gt; help people mitigate them.&#xA;&gt; &#xA;&gt; On Wed, Mar 11, 2015 at 3:57 PM, Aaron Voisine &lt;voisine at gmail.com&#xA;&gt; &lt;mailto:voisine at gmail.com&gt;&gt; wrote:&#xA;&gt; &#xA;&gt;     I&#39;m not convinced that wallet seed interoperability is such a great&#xA;&gt;     thing. There is a wide variability in the quality and security level&#xA;&gt;     of wallet implementations and platforms. Each new device and wallet&#xA;&gt;     software a user types their seed into increases their attack surface&#xA;&gt;     and exposure to flaws. Their security level is reduced to the lowest&#xA;&gt;     common denominator. I see the need for a &#34;fire exit&#34;, certainly, but&#xA;&gt;     we must also remember that fire exits are potential entrances for&#xA;&gt;     intruders.&#xA;&gt; &#xA;&gt;     Aaron Voisine&#xA;&gt;     co-founder and CEO&#xA;&gt;     breadwallet.com &lt;http://breadwallet.com&gt;&#xA;&gt; &#xA;&gt;     On Wed, Mar 11, 2015 at 12:46 PM, Gregory Maxwell&#xA;&gt;     &lt;gmaxwell at gmail.com &lt;mailto:gmaxwell at gmail.com&gt;&gt; wrote:&#xA;&gt; &#xA;&gt;         On Wed, Mar 11, 2015 at 7:24 PM, Ricardo Filipe&#xA;&gt;         &lt;ricardojdfilipe at gmail.com &lt;mailto:ricardojdfilipe at gmail.com&gt;&gt;&#xA;&gt;         wrote:&#xA;&gt;         &gt; i guess you look at the glass half full :)&#xA;&gt;         &gt; even though what you say is true, we should aim for wallets not to&#xA;&gt;         &gt; require those instructions, by standardizing these things in BIPs.&#xA;&gt;         &gt; let&#39;s hope bitcoin doesn&#39;t fail in standards as our industries have in&#xA;&gt;         &gt; the past...&#xA;&gt; &#xA;&gt;         There are genuine principled disagreements on how some things should&#xA;&gt;         be done.
