I do this (with OpenVPN / Android, but same idea) and the main factor that limits my own performance is the poor upload speeds of my residential cable subscription. For many residential services, you're looking at asymmetrical up/down speeds, and they usually advertise the higher download number only. This is normally fine since you most people download way more than they upload and don't run servers in their homes, but when you route everything through your home, you may be limited by upload speeds.
