My current best guess: A Hardware True Random Number Generator installed on one server combined with entropy broker to commingle all the entropy pools of the devices on my internal network into the entropy pool of that server and then serve that pool back to all devices acting as an entropy server. My intent is that if there is a deliberate weakening of certain entropy sources, that my pool is sufficiently different to at least complicate attacks which are guided by information like browser signatures. Maybe it's not a perfectly secure solution but hopefully my network isn't among the lowest hanging fruit.
