Nice list! These are pretty useful. I found the experience of using protobuf for frontend <-> Go communication to be good, since it forced me to do the work of 'writing my own protocol' but without all the encoding/decoding. There was some issue with naming in protobuf and Go's conventions though. To add my 2 cents: I think mining Monero is actually very reasonable (you seem to have thought through the impact on your users), and you've nailed the most important thing: making it opt-in. I'm fine contributing CPU cycles when playing a game, as long as it's in the foreground and I agreed to it.
