Poser 7 is self-contained within its program directory, so it would work without issue, except your preferences wouldn't move from machine to machine.  You may be able to get around this by using shortcuts back to directories on your removable drive. Installing SR3 on each machine with the drive plugged in will recreate the file associations, if they are needed.

I don't yet have any experience with moving Poser 8 around.
