I found a thread at the big bad AMV site of all the AMVs shown at Anime Boston 2008, complete with links to each individual page, where you can download a high quality movie if you sign up for the site (free, fast, painless... I did it). It shows who won each award and provides some basic info.
Hope you enjoy looking at these! I think "Unbreakable" is really great. I haven't seen many of the anime featured in it, but now I want to! Also, it's makes me all happy inside to watch it.
Also, make sure you check out Dead Fantasy I and Dead Fantasy II... they're awesome.
