Yes! It was Hans' brilliant idea to use libSQLFS ("a library that
implements a POSIX style filesystem on top of an SQLite database" on top
of SQLCipher. It has worked like a charm, in production use by 100,000s
of users in ChatSecure, Courier, CameraV (where we record and play
videos into it) and other apps.
