I'm putting a list together at http://wiki.winehq.org/DesktopMigrationProjects listing organizations who are migrating their users from Windows to Linux. I only list projects that have come out and said which Windows applications they really want to run on Linux.
Since these migration projects, if they end up using Wine, will be very good publicity for the project, it might behoove us to look carefully at whether we can get the apps they need running. I know Banco do Brasil's folks are quite happy at the effort put into Lotus Notes 5.x recently, so it is possible for us to make a difference. - Dan
