We're not talking about a consensus system here. Just a way to rate-limit
access to a broadcast network used by a small minority of nodes. It's
completely ok to simply change the PoW algorithm in the _highly_ unlikely event
someone bothers to build an ASIC for it. Since this isn't a consensu system,
it's totally ok if multiple versions of the scheme run in parallel.
