That's the chicken/egg problem. The only real clients I've seen right now are the python testing implementation, OpenDNS's servers, and the DNSCrypt implementation that OpenDNS released: http://www.opendns.com/technology/dnscrypt/

Looking at one of my CurveDNS logs for the last few days and doing some very basic math:

    $ grep "query too small to be DNSCurve packet" *.s | wc -l
    27539

    $ grep "DNSCurve shared secret" *.s | wc -l
    2282

    2282/29821 = .07652

So about 7.6% of all DNS queries are being answered via DNSCurve. Doing reverse IP lookups on the querying servers, nearly all of these requests are coming from OpenDNS.

btw, gdnsd dropped DNSCurve support in recent builds, so it's only curvedns now.
