The problem with Dean Edwards packer is that it unpacks using JavaScript and some "eval" magic. I don't think it is a good idea, because it dramatically reduces the load performance of large javascript applications. And this each time. In this case it is better to leave it to real, directly executable JavaScript IMHO.
