I have multiple XP VMs. The XP bit here is irrelevant, could equally be multiple Debian or Vista VMs. One for my personal stuff, another an image of a client machine. I keep all my files, OS X, XP personal and XP client, in my OS X tree structure. There are file associations telling OS X that when I click on a .ppt file, to open PowerPoint in my personal XP VM. I always have the option of using "open with..." What I can't figure out is how to distinguish between the PowerPoint instance on my personal XP VM, and the PowerPoint instance on the client image XP VM. This gets annoying when I have the client image XP VM running, and I double-click on a .ppt file in OS X Finder, and my personal XP VM fires up. I would like to change the automagic file association for .ppt (and .xls, .doc, etc) to not fire up the related app, but to ask which instance of the app to run. What would be ideal is something that asks if I'd like to run the selected data file in PowerPoint on XP personal, PowerPoint on XP client, or in OpenOffice in OS X. Of course, this will only work after I've figured out how to discern which guest OS is hosting which instance of the app. Any ideas out there?
