It actually is possible to render those pages in phantom at scale, but it's not very elegant. It seems like something like env.js would be sufficient to render

It actually is possible to render those pages in phantom at scale, but it's not very elegant. It seems like something like env.js would be sufficient to render the page, though. I think other people have done that, although I haven't seen a framework that makes it natural. Meteor and others would be in a great position to build such a framework.
