I think its a great feature.  
Every little bit of data, be it a post, a quote, a song, a whatever file it is: generate it, and then delegate read, write and executional access.  
Either for free or with a paywall or just by sending a link or giving access to certain keys.  

I am not using it that much yet, but thats for other reasons.  In general I think its "thäää fiutur".
