It occurred to me that one may wish to restore a wallet on a compromised computer. Perhaps they need to prove that a payment was received.
Regardless of whether this is a good idea, is it possible to use a mnemonic to restore a view-only wallet, in terms of:
the required math to create a mnemonic for a deterministic viewkey, and
the code currently in place that parses and processes a mnemonic to create a wallet.
