Their free account gives you DNS hosting, and 5 free subdomains (from your own domain, or from their large list of donated domains) with A, AAAA, CNAME, NS, MX, TXT, SPF, LOC, HINFO, RP, and SRV records. They also do dynamic DNS and backup DNS.
The premium account gives you from 25 to 500 subdomains, 3 to 30 stealth flags (basically the ability to add your own domains to their system, without listing them on the public list for others to add subdomains to), and wildcard DNS. Their premium accounts range from $30 to $600 a year.
I'm just trying to gauge interest, as I recently sent the admin of the site an email requesting that he accept Bitcoin. I use their free service right now with my own domain, and I've never noticed any downtime.
