Plausible deniability the next step
 

[ ] Allow tunneling

New feature:

This will allow your node to tunnel a download request to another node. When you download from an IP you wouldn't know if that file is actually residing in that persons hard drive or that they are just tunneling from another node.

You do not have to even enable the feature just the fact it is there means that a person downloading from you cannot be 100% sure that the file is on your drive or not.

No more mass John Doe law suits. To ascertain who had the file a log of the IP would need to be obtained. That in its self would be difficult, as you cannot prove that they had an infringing file to start with. Then depending on that log other IP logs would need to be obtained if the first log shows data transfers to other IP addresses. Each IP address would need to be scrutinized to isolate the IP that originated the file.

This would mean that no more interns sitting in front of a PC writing down IP addresses for mass law suits.

I do not know how you would work the mechanics of this idea but even if you can achieve a few percent of downloading done via tunneling then you have plausible deniability so long as someone looking at your node cannot tell if you are tunneling or not.

Let me know what you think :)
