d) Do not get upset or disappointed if your new algorithm / implmentation
does not become popular. Cryptography is a fairly conversative bunch
in practice, and if your algorithm is not well known, and greatly
cryptanalyzed, I don't think many people will want to become bleeding edge
testers / victims.
