Several European TLD's now support DNSSEC (including .eu, .cz, ch, .se, .be, .nl). For the large TLD's (.com, .net) this would take another one or two years, but it would be a big boost for hosting providers if Plesk 10 will implement this. Bind 9.7 can automate the key renewal process.
Is there in the meanwhile any news on when Parallels would implement this?
