I've recently learned that this is possible... the jist of it is :
The buyer generates a keypair and gives the public key to the seller.
The seller generates a second keypair seeded by the buyer public key.
The seller then sends the offset between the keys to the buyer and the buyer applies the offset to his original private key and it ends up being the new vanity keys.
Graingert on IRC pointed me to a thread here, but I can't recall the link. Something about type 2 deterministic keys.

Sweet. From what I've read so far it's pretty simple and can be done quite easily.
Thanks
