has anyone tried using junction.exe to set hardlinks to a single instance of the WOW subfolders, leaving the config.wtf and Interface as a real entries?

this would mean one instance to patch and possibly the disk access benefits of a single copy but could give the flexibility of many.

I would try it myself... but after a day at work managing a huge Active Directory... I just like to play! (and with a baby daughter and pregnant GF I don't get the time anyway )
