Yes, I am phasing down the XTB business. I spent over a decade working pretty much 7 days a week and up to 12 hours a day designing, producing, and supporting the products as well as responding to hundreds of questions from other X10 users. I'm just burnt out. Over the last year I've finally been able to catch up on some things around the house that had been put off for years.
Status: The XTBR and XTB-523 will remain available for the foreseeable future. There are only about two dozen XTB-IIR/+ left, so they will be discontinued soon. I will continue to support any units that may need repair.
If anyone decides to step up to take over production, I'd be happy to work out a deal with them. For a new design, I think a XTB-USB (USB version of the XTB-232) would be a good product.
Regarding the Forum disappearing, that was a result of Bluehost upgrading the forum software. I tried the changes that should have made it compatible with the new software, but that didn't work and caused problems for my basic website. Since there had been very little activity on my forum over the last year, it wasn't worth the effort to try to resurrect it.
Further thoughts: If someone is willing to step up to take over production and sales, I'd be willing to "batch kit" some of the products. The PCBs and machined cases are gone, but I still have many of the through-hole electronic components left over.
