Ah, I see that you *can* successfully have multiple profiles running at the same time, I was just doing it wrong:
Let's say you have 3 profiles: profile1, profile2 and profile3
Simply run these commands to run each profile in a separate window:
firefox -no-remote -P profile1
firefox -no-remote -P profile2
firefox -no-remote -P profile3
