[Q] Downloading Custom ROMs or Firmware in a Peer to Peer fashion? topic

I was trying to find a stock firmware for my device, which I found, but then I was thinking.

Wouldn't it be easier if there was a 'piratebay' for everything Android? What I mean is, rather than downloading say a custom rom from a central server. wouldn't it be cheaper and faster to download in a peer to peer fashion?

I was also thinking that there needs to be a central repository for all custom roms and firmwares. Otherwise, it hard to find what you need. At least in terms of stock firmwares.

Has it been done?
