Agreed. But how do I implement this with the QT ? Is this currently possible, or a future possible feature ?
Not currently possible. (We'd have inherited it if it was in bitcoin core, alas not there either.)
I balance the two technologies.
bip32 addresses for my masternodes, a.k.a. long-term storage
win-qt for day-to-day dash (small amounts)
I've built a tutorial for building your own address/key chains here:
http://en.wiki.dashninja.pl/wiki/DIY_Deterministic_AddressesIf you're not familiar with how wif's work, it's pretty simple.
A wif is the private key that controls the coin at an address.
If you have the wif, you can import it into (just about) any wallet and control (move) the coin.
The library 'pycoin' and the command line 'ku' build wif's (and their associated addresses) for you to use as you see fit.
See the links at the bottom of that wiki page for more detailed info about bip32.
