DNSCrypt provides channel security. The rhetoric surrounding it for a long time promoted its use as a replacement for DNSSEC, and that promotion faltered because it's not an obvious replacement (DNSCrypt and DNSSEC do different things).

As a replacement for TSIG or SIG(0) between stub resolvers and upstream validators it might have a use. But "replacement" is the wrong word, because nobody secures those channels today; this leaves DNSCrypt looking like a solution to a problem that nobody is really acknowledging out loud that they have.

DNSCrypt is quite clever, I think. I don't think it's a lack of cleverness that is stopping it from making progress. OpenDNS arguably have a better shot at encouraging its deployment than the original authors, since OpenDNS have paying customers to talk to (and are no longer talking about it in terms of replacing DNSSEC).
