It would enable investors the ability to generate a wallet address completely off-line, then print their credentials, like they can on a normal blockchain. It enables real cold wallets.

I've created cold wallets on graphene-based chains, so it's quite possible now. Here's a simple mechanism:

1. generate your public/private key pairs offline (I'll refer to these as your cold keys).
2. use an existing account to create an account with your chosen set of cold keys (you only provide the public keys in this process).

The resulting cold wallet account has a name, but there's no real problem with that, IMO.
