What about SIA and syscoin storage facility?
SIA mean to be decentralized storage and have heard that they have also successfully tested their platform. I think we need decentralized storage for all hosting and cloud storage needs.
Sure, but I think the Sia storage is a bit convoluted, I mean the storage contracts are not interchangable AFAIK. And you will still need the same hash from account/pvkey to be able to download the file, and I still not sure how fast is a sia download.
And you end up with the same issue of where to point these keys/contracts just like KAT host the magnet hash and the Torrent files.
