I encourage all developers - provide a setting to allow people who share their files to 'NOT SHARE' with any particular user(s) who do not. For example, KAZAA LITE provides a user 'participation rating'. Those with a rating of 0 typically don't share, don't take messages, yet clog my upload bandwidth helping themselves to my files. I'm happy to share but p2p kinda sounds like 'share n share alike'. I'd like to be able to cut off selfish folks who don't share so that the generous people can have better access to my shared files. People who take but aren't willing to share, in my opinion, are rather....selfish... Let's have some means of 'encouraging' people to share. We can't force them too but a setting as I've described above would help.
