Anyone playing with the ROKU Rest API?

Is anyone playing with/interested in using the REST API for Roku?

ROKU External REST API
https://developer.roku.com/docs/developer-program/discovery/external-control-api.md
The External Control Protocol (ECP) enables a Roku device to be controlled over a local area network by providing a number of external control services. The Roku devices offering these external control services are discoverable using SSDP (Simple Service Discovery Protocol). ECP is a simple RESTful API that can be accessed by programs in virtually any programming environment.

Looks pretty slick. I will probably start banging on this soon for my home media setup (KODI & MythTV).
