That's an awesome question! Yes, any arbitrary protocol can be tunneled through an Ockam SecureChannel. So if you have a device that produces readings as some binary structure or JSON or some other encoding ... a secure channel can deliver that data end-to-end protected to your backend application. You can even tunnel high-level protocols through a secure channel, we recently tried tunneling SSH through Ockam to create secure remote access to a machine that is behind a NAT .. and it worked like a charm.

To make this simple and transparent, we're building a feature called Transport Inlets & Outlets. With that you can easy create a proxy (either on the same device if it has an OS or in a nearby device) without modifying your original device application - the code of your sensor. There is an open PR on TCP Inlets & Outlets (portals), if you're interested: https://github.com/ockam-network/ockam/pull/1756
