Arch, if you can in fact follow the Window Vista documentation and define a Windows symbolic link that results in you program referencing file A but actually reading or writing file B just as a UNIX symbolc link does then the features would seem to functionally equilivent no matter the internal underpinnings. Your rebuttal is too devoid of supporting facts to allow me to determine why your agrument should be accepted.
