Thats probably the reason for all the hoops to jump through - the content providers (and Dish) don't want your buddy to have access without paying.
Sling stand alone (especially pre-Dish Sling) didn't care as long as you were buying Sling boxes and viewers and didn't have to worry about making providers happy.
Disagree...the Slingbox standalone client SW requires a logon and password and only one computer can be logged onto the slingbox at one time via the client (or mobile application). There is no option to setup multiple users with their own individual logon and password.
