To clarify, do either of them think this is exclusive? Because if not, then this is a slightly different problem. Instead of trying to figure out if/how to juggle, this becomes a question of "Do I want to have a 'big relationship conversation'?"
In this case, the issue becomes whether a simple "I am dating someone else, too" conversation becomes the dreaded "How serious are we?" which too quickly degrades into the "are we getting married?" conversation, which I assume you are no inclined to participate in (Because none of us are inclined to that, really.)
So, how to have the conversation of relationship status without escalating to serious relationship status? I'm not sure you can. So, I would fall back on the multiple avoidance strategies suggested earlier in the thread.
Edit: Okay, some more mature responses to the relationship status conversation: just because you don't have it doesn't mean that it is not a real topic that is necessary. I say, tell them both that you are seeing someone else and let it fall out as it will. Unless you think one of them is serious marrying potential - assuming that is still interesting to you. Then dump the other. Given your history, my guess is that moving into a single, exclusive relationship right now is not your ideal situation. So tell them both. Avoiding just ups the ante and the likelihood you get 'caught' and you have no control over who leaves upset. By being open now, you can say you are doing nothing wrong, and if one of them freaks, you have a good clue into what the relationship would have been like six months down the road.
