In the multisig example located in the developer documents everything is listed in sequence in a single client "session" so to speak.
The way I understood multisig to be useful is that 'rootKeypair' (person A) is able to enable multisig on the account with 'secondKeypair' (person B).
Then a week later (for example) 'rootKeypair' creates a payment. Following that 'secondKeypair is able to sign the transaction N minutes later from a separate client when they're ready to approve.
Is this correct? If so, how does the transaction get moved between clients? Does it happen on the network?
