You can follow HDW progress in bitcoinj on this branch:

  https://github.com/bitcoinj/bitcoinj/commits/keychain
   
I've been working on it for a couple of months now. Electrum (Thomas V) is also making good progress, and Trezor already uses HD wallets. I think most popular end user wallets except blockchain.info and Bitcoin Core will support HDW soon enough.

At any rate, as Gavin said already, the best way to make a feature you want happen is just to write it. Devrandom is already working on a watchdog service, as is another group (TrustedCoin), and that's an obvious use for multisig/p2sh. They have API's already, it's just a case of standardising them once we get more experience.

Speaking from the MultiBit perspective, all future protocol development (with the exception of critical security and network compatibility fixes) will be put into a HD wallet. Over time we want to see "MultiBit Classic" gracefully retire and be fully superseded.

Right now, HD is not out there but there is a lot of work going on between wallet developers to harmonise on HD implementation through BIP32/39. The result of that work should see a significant migration away from random private keys. 

Thus it would appear likely that by the time this protocol sees widespread use the presence of HD is likely to be rising fast or possibly dominant. 

At MultiBit we anticipate a release of HD code within 2 months, with private beta occurring within weeks. Trezor and Electrum may be earlier than this. As far as I am aware both Hive and Haskoin are committed to HD.

If anyone wants early access to the alpha code, let me know and I'll make the arrangements.

Right now, HD is hot air.  Let us end the pie-in-the-sky assumptions
about how HD will save the day, with zero code to back it up.  Bitcoin
Wallet purportedly fails to rotate addresses, a privacy ugly, because
of this Waiting For Godot situation.  An attempt to add a simple,
stateless RPC stalled because we are all Waiting For Godot, also:
https://github.com/bitcoin/bitcoin/pull/3520

Until the major user wallets and bitcoind have -basic- HD support, it
is premature to build anything on top of HD.  We really have no clue
at this juncture how difficult will be the HD rollout.
