It would be extremely useful for Wubi to be able to use a BitTorrent connection to download installation data or alternatively allow Wubi users to select an already downloaded ISO to use.
Currently when new releases come out it takes hours for Wubi to download all the required installation files. Using BitTorrent, and the internet connection at my university, I can download the full CD image in about 20 minutes.
Now if only I could download at that speed inside of Wubi using the BitTorrent protocol...
OR
Use the image I downloaded with Wubi...
