I had also thought that this plugin would work with WF2IR based on the title. Well, I dug in and modified it to also work with my IP2IR, which should be the same as the WF2IR and it has been working great this past week. I also added in some error checking and messaging for end users.
Anyhow, I PM'd Airedale on Sunday to see if he didn't mind that I post the files here but I haven't heard back and then noticed that he hasn't been on the forum in months. I guess my next step is to pull out his code and publish it for the older iTach devices only.
If anyone knows how to reach him outside of the board, please do.
