You could mount a case insensitive proxy to the whole file system
(starting from /) somewhere in .wine, maybe .wine/drives/x or
something like that and have wine access files only through .wine and
never from outside.
I'm pretty sure this could have performance penalties but I guess we
will have to find out how much performance you loose by using this
approach using some benchmarking tools or writing some test code for
