I remember looking at this a few months ago, and I wasn't impressed, although I can't remember the details any more. I do remember being annoyed at how long it took to get to meaningful details beyond "the belt solves everything and I'll talk about the belt later" - to the point where it felt like he was trolling (getting a laugh at wasting everybody's time). If I'm feeling masochistic later, maybe I'll take another quick look at it...
edit: I read through some of the slides that weren't available last time I looked; it seems like there's some lack of understanding of the normal way of doing things (and there's use of nonstandard terminology for no obvious reason), some oversimplification, and some stuff that just blatantly won't work for the vast majority of real code. The whole thing feels like somebody is trying to reinvent the wheel, without quite understanding it first.
