Sorry for bothering the list once again with my humble suggestion but coming back to ClearCase: why not implement the concept of a view:
1. You specify a set of rules which say which file is seen if there is a conflict. 2. In the case discussed here you also specify where to write.
On mount these are read by a daemon and the kernel shovels all file I/O to this daemon into user-space. The daemon goes through 1 and 2 and does the actual file I/O.
May be rather slow but very flexible. And accomodates for all subcases - union filesystem, transparrent mounts, versioned filesystems, etc.
Per-user functions can be implemented via preload libraries.
