SNI or a dedicated IP is not required if you use a single certificate with multiple domain names. Also you don't really hand over more sensitive personal details than you already provide to most web hosting companies. The only additional requirement was a copy of my personal id. Finally, Chrome does support self-signed certificates authenticated using DNSSEC and there is work going on to make that a standard (DANE).
