Proof of work will be set at near zero when the server is not under
heavy load, and when it is under heavy load, you don't care if a
smartwatch takes five minutes to open a connection. 

While the consequences under both extremes of very low and very high server load are reasonable, you're not accounting for the very common case of servers by design running very near max capacity during peak load. The margin between "all ok" and "engage full DDoS defenses" can be small. 

So the question is then how do you scale PoW difficulty in such noisy and low margin environments? Will your smartwatch need to run hot for a minute a few times a day, every day?
