How is this coming along?

I just came across the XRF which, while a bit costly, might work in your environment given that it's tunable over such a wide range (and probably has power output higher than legal for the US). The developer asked me for help doing an XRF to X-10 RF Gateway which only took a few minutes to explain. I can ask him if they've had any experience with TIG. Maybe they could even test it if there's someone nearby with TIG.
