I've used jungledisk for a long time and felt they've really squandered a great opportunity (or maybe getting acquired by rackspace _was_ the opportunity in the first place). I agree the jungledisk UX could be better, but the idea was good: run an service on the user PC that works with s3 and behaves like a hard-drive and make the user pay amazon directly for the storage and bandwidth "a-la carte." There really isn't a need for servers, why not just s3 buckets + the user machines? I am surprised there aren't opensource solutions that just take s3 keys and make a virtual drive. Or are there?
