I just mined a few SC and now I'm also tried to participate as a host, but after 2 days, I didn't received any contracts.
Also the usability leave a lot to be desired, in a post before I read something about the html implementation, which sounds really nice, so download plattforms could also use your services. maybe you could also integrate some gui for some download websites for musicians to upload their music or maybe some for movies and stuff like this. I guess this could be a community, which will push your services, even if we live in the century of spotify and other streaming services, I guess there still would be a market.
Also some partnership with a direct SC seller would be make it much more easier to handle for otto normal citizens. I would create a html implemantation which is put on top of your chain.
