I have an issue that when using bandwidth intensive applications like FTP/bittorrent/newsgroups these will often use all available bandwidth and consequently things like web browsing/video streaming/skype calls will become stuttery/unresponsive.
I would like to be able to allow the bandwidth intensive apps to be deemed lower priority, and only to use as much bandwidth as is not currently being used by higher priority applications.
I don't want to have to manually pause a download when I start watching iplayer for example.
Is there some way that I can do this? Currently most of my bandwidth intensive stuff happens on one machine and the video streaming happens on another, but both machines are used for browsing, so I would like a solution which works by giving priority not traffic on the same machine as well as traffic from different machines.
