Very good points Linda. I agree too. I've gone into many offices where you just need to get into their system to see what's going on and if you are too rigid, needing them to use your software, many will turn away. It is hard for them to change small things, so giving up total control is too much.
I use both LogMeIn and GoToMyPC. You have to set up gotomypc on the host computer before using it as well. It also has two sing in's, one at the website and then one to access the host. That password can only be set up at the host.
