There is not currently a way to scroll the devices from the desktop.
We are trying to figure out good methods for providing some functionality like this - if you don't mind describing when and what you would use it for that would certainly help.
The reason why i would like to use a remote scroll function, is for the reasons that i have more then one device connected at a time (5), and it can be a bit of a job to scroll through each device. To go to that targeted area.
So when i have all my devices infront of me i can scroll all the devices at the same time. As most content and or functionality of a mobile website will be lower on the page thus needing to scroll for each page / device.
