Cool but wouldn't it be very hard to scale a service selling large files on this when you can't dedupe content?

This is only one area of application of this technology. The possibility to link the file access to the transaction is important here. File deduplication and piracy issues are applied tasks of those services that can be created using these features. We will provide such features with all the necessary options, for our part.

Hmm, maybe I'm missing something but wouldn't it be impossible to dedupe the files if they have to be encrypted with the users public key before storing in IPFS? And without that feature what sets this apart from DTube for example that just posts IPFS hashes to the Steem blockchain?

The hash is encrypted with a public key. The file itself is encrypted using AES-256. The hash is not in the public access.
