Thus I have learned to pay for software, often dissuaded by "free". The money has to come from somewhere, and "he who pays the piper names the tune."

The primary use is for the local network where this is rather a nice benefit – no CDN is going to help when you have a fixed amount of bandwidth divided by every Windows PC in the building.

It'd be interesting to see how it handles nearby node discovery since e.g. the average cable modem user often has far more bandwidth in their neighborhood compared to their ISP's uplink.
