Transparent intranet/internet access
It would be interesting to have a single FQDN for accessing the file share, accessing the local servers when I'm in the corp network, and the cloud files when I'm outside the corp network.
Maybe something along the lines of having some kind of split-DNS, where the corp DNS servers would resolve StorageAccount.file.core.windows.net to an internal server.
The goal is to have local access while logged in to my corp network, and cloud access while away from the office, in a transparent way (i.e. same network drive).
