Exchanges and web wallets do not need "cold" and "hot" storage. They need 2-of-3 multisig lock.

1. User's funds are locked on 2-of-3 multisig transaction (P2SH or directly, does not matter).

2. Key A belongs to user (similarly to Blockchain.info, service may backup the encrypted key, but user loses key when forgets the password).

3. Key B is stored on web server, unencrypted.

4. Key C belongs to technical staff of the service. This key is encrypted by staff's password and only stored on personal computers of the staff.
