I found myself accidentally starting two large uploads, and since they are single BLOBs, I cannot easily stop/start them, potentially loosing much time. However, I prefer one of those processes to get the priority and give it, say, 80% of the available bandwidth.

With most file sharing tools it's relatively easy to limit or broaden the bandwidth. Is it also possible to do so for a running process? This is on Windows 7, but would equally be helpful on Windows 2008.
