Another great feature would be the ability to bond different connections together (e.g. ethernet, Wifi, Cellular) to send the ip packets through these channels concurrently. This:
a. increase bandwidth,
b. reduce hiccups,
c. and enhance security as it would confuse statistical analysis of traffic.
Indeed, it is for these reasons, and it's fantastic application, that Speedify has become my VPN of choice.

If all these three features get implemented, I believe you would end up with a very formidable service, way ahead of the crowded competition—as you would offer greater responsiveness, speed, and security.
