I'm announcing it again here in case you missed the it on Linux Today and LXer last week. There have been questions posted here on how to do system-wide sharing of applications under Wine in order to save drive space and simplify installation. It is possible and last year I started writing a bunch of scripts to make it easier. Basically my scripts share a Windows application between different users on Wine by using Aufs to mount the common files in a read-only branch with a read/write branch in each user's home directory. The main installer script is unfinished but the tests I did during development at the command line indicates that the theory behind it is correct. The installer has to do a lot of text processing to get the Windows application menu entires (freedesktop.org XDG files) installed for each user. This mess was done via a bash script which is tedious for text processing. It needs to be reimplemented in something usable like Python, Perl, etc. Read the blog posting (http://jhansonxi.blogspot.com/2009/08/introducing-winesharer-so-pre-alpha-it.html) for more information.
