S3-backed, Mac-specific backup tool. Looks nice, and well-thought-through.

"[s3fm]... lets anyone run a streaming radio station, with just a folder of MP3s. Put those MP3s in an Amazon S3 bucket, and give your friends the S3 FM link."

"All it takes is a single call to Rake and you're backed up on Amazon's redundant, secure systems."

$99 desktop that has 4gb of internal storage and uses S3 for the rest. Distributed thin-ish clients, much like were promised in the golden age of Java. Etc, etc, etc.

"In case you missed it, let me repeat this: we will be charging the owner of the bucket for 403s and 404s, since they consume system resources." S3 jumps the shark, mayhap?

S3’s early success makes you think that if the on-demand infrastructure can be delivered at an affordable price, the cost of setting up an online business is going to decline even further, perhaps prompting a whole cycle of new entrepreneurial activity.
