Filepile is having bandwidth problems. I think Filepile really is a next-generation tool that allows people to communicate more beyond text. It's the right model. And I think the technical problems they have to overcome are interesting. It fits in with the whole Napster, P2P thing. And this link highlights one of the cool things about MetaFilter: the founder is an early member of MetaFilter and weighed in with the inside story. Cool.
