MirrorBrain is an open source framework to run a content delivery network using mirror servers. It solves a challenge that many popular open source projects face – a flood of download requests, often magnitudes more than a single site could practically handle.

This could provide an excellent and cost efficient alternative to using services like Amazon’s CloudFront (which is really great, too, as my preliminary tests show).
