We have finished working on connection Casper API to NEO and after internal testing we will roll it out for you to try. Providers, in their turn, will be able to store files from either Ethereum or NEO, where our MVP is currently operational.
P.S. for those who are eager to already try it out, you can get it from our github https://github.com/Casper-dev/Casper-server
Stay tuned for more!
