If you controlled almost the entire network you could see where a message showed up first, but you wouldn't know where it was going. And since the app was mostly desktop only and kind of slow to deliver it would be used more like email where it could be hours before you see a response.

So maybe kinda but you don't have a lot to work on. And nodes don't have persistent IDs so if they were on a VPN, CGNat, dynamic IP, you'd have a hard time tracking them over time.
