Yes, this product historically was a BeOS product, and eventually it became cheaper to put together a version of Haiku with no show stopping bugs for their customers on hardware you can actually buy than to try to find hardware that would still run an obscure 1990s operating system.
The very first versions of this product are essentially BeOS, plus an existing MP3-player type application, plus a little bit of software glue, the right off-the-shelf hardware and the know-how to use it for radio broadcast.
It's definitely one of those products some HN regulars would dismiss as "I could basically make that in an hour". Me too. But, after an hour nobody else can maintain it and it doesn't work on anybody else's computer. The hard work is in turning that into a product that generates some net revenue, which is mostly non-technical work.
They have another system at the bottom of the page for a mere 1600 USD.
