Create a way to access to files uncrypted

I am starting a new company and I am interesting in this project as a collaborative tool for document edition. My most important blocking point is that I cannot access to the files in the drive but through the web-browser. I need to access to these files somewhere : on server side (mounting the encrypted database as a drive) or on the client-side (software for synchronization) or using local-instance with decentralized solution (#288) .

I know you you mentioned on the FAQ that the client side synchronization is widely requested. Have you any ETA on this solution ?
