I want to be able to write to OPC tags via `system.opc.write*` functions which is easy when you have a single gateway, however to write a wrapper function that allows for more complex gateway networks with remote tag providers (RTP) (and perhaps nested remote tag providers) is _significantly_ more complex.

I've hacked this before by reading the remote tag provider details from the internal config db and this works for a gateway with an RTP pointing directly to a TP, but if there are any hops to other GWs it would fail (assuming this is even a thing). It's also not nice reading from the config db.. Is there a better way to do this?
