You can use $interpolateProvider to change start / end symbols used for AngularJS expressions:

var myApp = angular.module('myApp', [], function($interpolateProvider) {
    $interpolateProvider.startSymbol('[[');
    $interpolateProvider.endSymbol(']]');
});

and then, in your template:

Hello, [[name]]

Here is the working jsFiddle: http://jsfiddle.net/Bvc62/3/
