| I was contacted off-list by another registry who have implemented an
| extension very similar to mine. Their extension provides a mechanism
| whereby the client includes the expected fee (previously obtained by
| performing a lookup) in the command. The server can then reject the
| command if the fee submitted does not match what it calculates it to be.

| This ensures that both client and server agree what the fee for the
| transaction is, before it takes place.

| I very much like this idea and am planning on incorporating it into the
| next version of my draft.
