My parents were divorced, and I witnessed some of thier friends getting divorced. Through that experience -- everyone eventually chooses a side. I think it's great you want to remain neutral, and I think you should definitely keep the kids playing together -- theirs are going to need it a lot! If you get together with one parent or another, try to keep everything you say pretty neutral. You could even be up front and let them know you won't be choosing sides, and hope to remain friends with both. I wouldn't communicate through the kids, as they will probably be getting a lot of that. Offer support when it's asked for, and offer friendsip when it's not.
