In short, yes!
We are plugged into Project Argonaut and pay very close attention to the development of FHIR standards.
We are fully prepared to support FHIR integration. We are finding that the implementation of FHIR (and the ability to support it) is still many months away for a variety of major EHR vendors, but nonetheless, Redox is ready to go.
The same way we support HL7v2 or custom web services today, we will support FHIR when it is in use.
