I can think of many ways it could be done - I'm just wondering now how it is done since you brought it up. I have solved the question of knowing which one is running after an application has started. Your original question was a bit ambiguous as to that matter, but now that we've cleared that up you do have a good question which is, "If I launch a Windows application from OS X with a Parallels environment that has multiple Windows VM's, which VM is selected to run that application and can I force it to run in a preferred VM?".
