Perhaps I'm off target, but how would this compare to guacamole? We've looked at guacamole as a potential solution to our problem. We need our user to log into a third party system with their username) password. Then we want to take over and drive the session selenium-style.
Sounds like you want someone to log in to a remote system then take over and drive it selenium style. Is that right?
Well, I'm hearing you right, then this (BG) is definitely a potential solution for your problem. I think it would be lighter weight than Guac since it only runs a browser (not a whole desktop).
