A nice terminal integration feature using Distributed Objects or apple events to talk to (or instantiate and talk to) Sublime Text 2.

This is the best (and only way) to achieve seamless terminal integration on OS X. Pretty much it's a separate shell utility which is a DO client for your app (which is a DO server). It then pipes data to it, tells it to open a file, etc.

This is how the TextMate "mate" utility and the BBEdit "bbedit" shell tools work.
