Electrum (Thomas&#xA;&gt; V) is also making good progress, and Trezor already uses HD wallets. I&#xA;&gt; think most popular end user wallets except blockchain.info and Bitcoin&#xA;&gt; Core will support HDW soon enough.&#xA;&#xA;Interestingly, Blockchain&#39;s android wallet is based on Android Wallet /&#xA;bitcoinj.  So with HD in bitcoinj we would get Multibit, Android Wallet&#xA;(Andreas Schildbach&#39;s) and remove one roadblock to Blockchain going HD.&#xA;Electrum HD seems more or less ready.  So I&#39;m optimistic that we&#39;ll see&#xA;a pretty fast transition to HD for the majority of the user base.&#xA;&#xA;HD is important for some multisig flows, including the watchdog type&#xA;where you want to detect change going back to the wallet.&#xA;&#xA;&gt; &#xA;&gt; At any rate, as Gavin said already, the best way to make a feature you&#xA;&gt; want happen is just to write it. Devrandom is already working on a&#xA;&gt; watchdog service, as is another group (TrustedCoin), and that&#39;s an&#xA;&gt; obvious use for multisig/p2sh. They have API&#39;s already, it&#39;s just a&#xA;&gt; case of standardising them once we get more experience.&#xA;&#xA;We have a proposed flow for watchdog type multisig&#xA;here:&#xA;&#xA;https://cryptocorp.co/technology.htm&#xA;&#xA;and a reference implementation off the Electrum 2.0 branch.&#xA;&#xA;It actually works just like a regular spend from a UX point of view,&#xA;unless the watchdog decides that it needs a second factor for a risky&#xA;transaction.  With a risky transaction, the user just gets a&#xA;callback or enters an OTP.&#xA;&#xA;-- &#xA;Miron</html></oembed>
