I really want to use Plume... but I don't want my WiFi network to depend on "the cloud". I don't see any reason they should need to upload data about my private internal network to their servers. It means I can't trust them. If they ever went out of business, got acquired, or otherwise shut the service down I'd be left with a bunch of bricks too. Does anything else do the same kind of mesh dynamic frequency allocation, but without requiring any kind of cloud service?
