Here's a nice reference on the traps awaiting anyone who wants to write 
a union filesystem:

Also note that in the case of Wine a union filesystem does not solve the 
problem of the registry since it would not know how to merge the content 
of the administrator's and the user's system.reg files. So to make the 
unioning complete we would need a union registry too (or make each 
registry key and value into its own directory/file!).
