seems like dns-o-matic uses dyndns-like update api. you can try it right now (using 1.9.2.7-d exactly)
create /usr/local/etc/ddns.conf according ez-ipupdate manuals, wðich is to be append to autogenerated /etc/ddns.conf
any these params will override autogenerated ones, so you should specify server=updates.dnsomatic.com with typical ddns.org settings
so, play with it, or i could patch ez-ipupdate to suit your dns-o-matic needs... some day...
