This is nit what I ment. The examples here are payment to keep active seeders. What I want is a way for client to negotiate payment for traffic. For example if one client downloads 13 KiB from another, i want a way for the second client to say 100 microsat per byte, and if the second client agrees, it starts sending sats and the second client starts sending bytes. After the 13 KiB is ttansferred, the total amount of sats paid to the second client should be 13000*0.0001=1.3 sats. Is this possible or complitely impossible on the lightning network? (I am talking whether the lightning network can do that. I am perfectly aware that there is not torrent client that does that.)
