Do you currently use remote IR control/distribution in your system?
Yes, in a loose sense. I do use a Harmony 890 remote that transfers the remote's RF to a few IR blasters for controlling hidden A/V components.
If not are you planning to add it to your system in the future?
No, nothing new in the near future. If I ever build a home, I'll probably integrate some basic home automation into the A/V system, though.
What features do you feel are important for IR for this type of a system.
Wide compatibility, DIY support, good range, reliability. It would be great if the industry would standardize on RF or bluetooth instead of IR for system control, since line of sight isn't always available.
