<https://wiki.ubuntu.com/DownloadService/Download> does not say
anything about which protocols the download service implements. (FTP?
SFTP? HTTP with digest auth?) But since it asks for an "url", I doubt
it would be any help for a torrent client.

It's not the only way. That could be handled by a geofence service: an
app could ask "wake me up for a moment when the device reaches {less,
more} than X meters from point Y".

Runtastic would then set X to 20 meters or so, and Y to your current
location. When you ran 20 meters, it would wake up, record the time
and your location, set a new geofence 20 meters around your new
location, and go to sleep again.

One problem with this approach is that users wouldn't be able to make
an informed decision. What would be the harm of saying yes? Less
battery life, but how much less? Nobody would know.
