Let's think in orders of magnitude here. Will moving template rendering from the client to the server increase server load by an order of magnitude? I might be wrong here, but if more than half your request is spent in a templating engine, something is seriously wrong. Moving your code to the client side seems like an incredibly lazy way to shave a few milliseconds off your request time. Not to mention your doing so at the expense of increasing initial page load for the user, and breaking the semantic web.
