Qwilt and similar products are really neat, but I don't think they've entirely panned out. The idea to do transparent caching at the network edge was hurt by the move to TLS everywhere, and there's a lot less cost incentive when things like Open Connect exist (eg. if Netflix will give me a rack that offloads XX% of my total traffic, how much additional traffic do I need this transparent cache to offload before it's cost effective for me?). Without transparent caching the economics get trickier.
It seems like their niche is as an easy to deploy, more traditional looking CDN that can run out in the RAN, which does still have value.
