Yep, that's a nice and promising technique. I'm currently working on a NodeJS project and I'm using EJS templates with Handlebars templates on the server-side and on the front-end. The benefit is impressive. I can deliver the same content on page-load and using fancy Backbone routing I manage to change dynamically the page without duplicating code logic. I'm reusing some components on server-side and client-side, so my templates will always render with the same context ( JSON ) but on different JS environments. Amazing how far can we go, just to satisfy Google and SEO guys.
