(Ditto developer here) Yes most definitely! We are rolling out a feature called Ditto Bus which lets you open reliable or lossy streams for arbitrary data flows between between your device and another in the mesh. Each stream flows over any transport available and will multihop via the most efficient path if needed. An early version of this is already available in the iOS SDK.

It's a powerful building block that can be used for proxying any kind of other traffic, either yourself as an app developer or if we end up providing proxy/VPN/other functionality as part of the Ditto SDK.
