I think $49 per machine is a lot. But the software interests me. The one thing I'd like to see is a speed comparison between rsync and this product. Also, is the underlying technology something that could be licensed?

For example, at CloudFlare we are generating 20GB of log files per minute and we need to move these around. Finding a fast way to do that is important. Clearly, CloudFlare could pay $49 per machine without a problem.
