Hello again,

sorry, got a bit derailed on that proposal.
But now I think its time to work on it again.

- Any objections to get a BIP-number for it? 
        If not, can I get one, so I can finish up the test vectors.
        Current version: 
https://github.com/DanielWeigl/bips/blob/master/bip-p2sh-accounts.mediawiki 

- I decided against extending it for future P2WPKH addresses
        I think that should be a separate account on its own, to reduce 
implementation work 
        for future wallets, that only want/need to implement P2WPKH accounts. 
And to keep it simple.
        Was someone working on the P2WPKH address format in the meantime? (ie. 
alternative for [2])

- We will also need a extension to the BIP32 serialization format[1]
        It should be possible to export/import a xPriv/xPub key across 
compatible wallets, and they
        should be able without guesswork, fuzzy checks or asking the user to 
import the correct account type.
        Thinking about some flexible tag-based backwards compatible extensions 
- but thats a different BIP in itself.


Cheers,
Daniel
