Not yet.

The account creation portion isn't there yet. Tonight I did the first successful key creation test though. There's an experimental section at the bottom of the import that let's you specify a username and then generate a seed + keys.

It went like this:

• My buddy downloaded the wallet, picked a username, and sent me the public key information.
• I took the public keys and created him an account using the create_account_with_keys_delegated command.
• He then logged into his new account using the private keys he backed up, and now has an active steem account.

He didn't have to goto the website - but it required someone with technical knowledge on the other end to create the account.

I'm hoping to put GUI's on this entire process so that rather than relying on Steemit.com's account creation, we can securely invite our friends.
