It would only be a matter of time for Dish to get most of the features from DRA moved over. There's always been the option to add a slingbox via the account tab in DO .. at least from my memory at least back to May ... and because the WebSlingPlayer is universally used, the controls are simply addressed from the server side .... server says "remote" you get remote .. server says "under-picture controls" and you get the under picture controls.. there are times when the command doesn't come down correctly, and the option is there to click on a "remote" button and up pops the on screen remote.
The way you know its not "intentional" is because when the icon pops up and you bring up the remote.. most of the important controls don't work or aren't mapped.. like DVR doesn't activate the "My Recordings" etc..
