I know some Linux images are distributed via P2P softwares now, i.e. Gentoo. Is it possible to update them via P2P? I think it will be interesting to add P2P methods to apt-get. Based on Bittorrents or aMule(of cause we need a console version), it won't be too difficult. Now, I'm going to do some research to find out whether it has already been implemented by somebody else.
