The v1 clients did not actually check the entire message. Only the
first four bytes. If they matched, then it reported a "possible
solution" message to the screen, notified the server, and then carried
on with the rest of the keyblocks. Only the dev's know what a v2 client
will do. I guess you could set one up to point at the test port if you
wanted to find out bad enough.
