I've been hot and cold on emacs over the years. I've used it enough that there is a lot that I really like about it and that I'm annoyed by not having in other editors. But that list of links is the reason why ultimately I have decided to spend my time in a different editor.

Yes anything is possible and people have done work that probably intersects with what you're looking to do. But rarely does anything just work.

I spend too much time try to make things work and re-implementing features that exist in other environments. I tend to use Textmate and Intellij -- although extending Intellij is such a heavy process that I pretty don't do it.
