Yes, I have. There are many projects out there trying to solve storage/distribution problems, MaidSafe being one of them. There is also Swarm, Filecoin, Storj, Sia, Decent, etc etc.
IPFS is a nice building block, and it gives us a lot of flexibility to build on top. It is also something that is already somewhat usable today, and a good starting point. I would like to be as pragmatic as possible, and if someone solves a hard problem for us, I am definitely interested.
