No mention of split-key in unedited OP... :-(
Thanks for your feedback, TheButterZone.
I have made some additional research into Vanity addresses generation and can now offer split-key vanity addresses.
The only question left is how to import a split-key PrivkeyPart into the wallet ? The simple "importprivkey" won't work.
If you want a split-key Vanity address, please contact me and provide one of yours pubkey.
To retrieve your pubkey :
Open the wallet's Console and type :
validateaddress
To import your privKey (regular non-split private key) :
Open the wallet's Console and type :
importprivkey
You will generate the private key? What are the assurance that you would not spend our bitcoins?
I bet on the same effect as with Casascius and other physical Bitcoins manufacturers. Names are made over time.
If you wish, I can also do a split-key Vanity address so you don't have to trust me with your privkey, but I'm not sure how to import those ones into the wallet yet.
OP use public key to generate an address so he'll only have half of the private key and the rest is yours,no chance for importing address with this way since privatekey contain so much of character which can't be guessed easily or maybe near to impossible,correct me if i'm wrong
You were wrong. I didn't offer split-key vanity address generation when I posted this thread.
But you are right now.

I just don't know how to import them yet.
I will update the OP to add split-key generation.
