From a quick look through remoteStorage, it looks to me like it's is focused on storage (and so appropriately named!), while Edsu is more explicitly a foundation for applications.

One place this shows up is that Edsu has a permissions model where other people can read and interact with what you've stored (within very tightly defined parameters), which is the basis for writing multi-user apps like, say, a distributed Reddit or Slack.

They both have the same model regarding the ownership of data though. The biggest difference there is that Edsu uses a Merkle tree as the storage, like IPFS and git, which has a lot of consequences in terms of how it gets used.
