I don't think it will be as popular as you think it will. I have played around with one of the older coins with a similar concept and found out that it puts too much strain on my network connection. Some of us still have really slow internet speeds and datacaps. The slow internet speed makes it almost unusable for people that want to store large files on my network and it would completely drain my internet connection to the point it was almost unusable. So, despite the fact that I had all of this storage available for people to use, I couldn't really share it with the community. I'm sure it's a good solution for people with good internet service though. But, there's a majority of people in the world that still have horrible internet.
