Domain Mapping - How can I add Dynadot as a provider?

I'd like to use Dynadot as a domain provider in the Domain Mapping plugin. I'm not afraid to write code, but I don't want to fork the official plugin.

Can you point me in the right direction on what hooks might be available that I can respond to? Or if they don't exist, can you add some that will let developers create their own domain provider add-ons to the Domain Mapping plugin?
