[QUOTE=Fuzzyboy;231569]It's a nice feature, but is it significantly different from the functionality you get from simple directory junctions?



From what I've read, once the junction points or symlinks are set up, there's functionally little or no difference in actual play.
However, there is physically only one directory on your system, so it takes up marginally little less space on the drive.
The main benefit would be patch day - just patch the one wow without breaking links, patching, re-establishing links, copying wow.exe files and then going.
