I would like to limit the speed of tranfers when I use my computer and at the same time let Transmission run at full speed when the computer is idle. In other words, when the screen saver activates/deactivates, run a script that change that unlimits/limits the speed.
I guess this could be done using Applescript (e.g., here http://swannman.github.io/scriptsaver/) so the questions is mostly if someone already has written such a solution so I don't need to reinvent the wheel?
