mmmh, this looks a lot like what i wanted to write, ref: media sharing.

konspire2b: a revolution in mass-scale content distribution

with konspire2b-based apps, you:
1. subscribe to channels that match your interests
2. go to bed
3. wake up in the morning to the files that have arrived on your subscribed channels
4. feel certain that the files are legit, thanks to konspire2b’s heavy-duty, automatic, digital signatures
5. unsubscribe from channels that disappoint you
6. build trust for a channel owner’s tastes over time (owners are completely responsible for what goes out on their channels)
7. spend the time that you used to spend searching doing other less frustrating things (see 8 for a suggestion)
8. start a channel to broadcast your own files
