Plasma-based space life!

Here's a cool article. Yeah, they don't want to call it life, but imagine... Actually, I recently read Iain M. Banks's The Algebraist, and that had an intelligent life form that was exactly this (well, as far as I remember) and covered several AUs in diameter. You don't have to be a hard-SF-only, keep-the-fantasy-out-of-my-playground type to find this very cool as something to speculate about.
