It should be noted that dustjs is not yet updated for node v0.6.x. I submitted a rather trivial pull request toward the end of October fixing the problem and another user has submitted one since then, but the author has not responded to either.

This makes me question how much the project will be supported in the future - but I suppose having a large company like LinkedIn invested in the technology is a good sign.
