No, Mustache only I'm afraid. The reason is that it's not actually using Mustache or any of the Mustache-based engines (such as Hogan.js) - it's using its own implementation. That's because almost all other templating engines are string -> string (i.e. you add data to a string template, and get HTML) whereas Ractive is string -> DOM. Microtemplates, EJS etc would have to be reimplemented as string -> DOM engines separately if they were to work with Ractive.
