robuntu I am sorry I have some really bad news. http://bugs.winehq.org/show_bug.cgi?id=10495 Wine really does not support multi user. There has been lack of developers and resources required to cure this problem. Wine itself only provides 1 secuirty level to applications being administrator. Implementing this is basically a large project to say the least. Now I do have a few reduction things. Some duplicate file hunters for Linux support hard linking to master copies. So reducing the overhead. Using lessfs for wine directories is another option. Basically no good option really. Normally while in migration I end up deploying a windows terminal server. And use that for the remaining apps.
