This was built by my buddies, including the author of the Gaia Flash framework. It showed up on lifehacker today so I figured it was as good a time as any to brag about it here. It's pretty damn cool. Yeah yeah, it uses Adobe AIR - logical choice given their expertise. Hope that's not too big a hurdle for y'all to give it a try. Thanks.
EDIT: changed "authors" to "including the author" - Steven built Gaia by his own bad self, really. Should clear that up :)
