Eric Meyer was recently in Uganda, where he experienced first-hand a very undesirable side effect of HTTPS. The area he was in was served by satellite internet access, and experienced significant latency (a floor of 506 milliseconds) and packet loss (between 50-80% was typical). In addition, there is a cap on the data that an account can use in any given month. Go over the cap, and you either pay overages or lose data access entirely until the next billing cycle.
