For Internet radio to feel as if I was listening to FM radio -- no/little impact on my LAN, works even if all my computers are off (except the Geode & modem), can be on all the time. I don't need or want visual feedback, fancy equalizers or mouse, just 2 accessible *physical* buttons. Picture a car mechanic with a crappy FM receiver if you will. The decoded audio signal plugs into the rest of my audio gear which is not PC-based. >> For play/stop & next controls I'd use a small USB gamepad-type or MIDI >> controller, > >That looks like the most difficult part, because offhand I have no >idea how to interface those input devices with a tty. The point is not to need tty or network client/server messaging. I query a USB device directly, never leaves the Geode. I've done more complex stuff before, www.hackerdjs.com, and have lots of gear just lying around, forget about that part it's a distraction. >> I cycle between 3 hardcoded stations using 128kbps CBR so that's the only >> codec I need. >> >> - what's the most nimble stream+mp3 solution? > >mpg123 is probably the fastest one, although all of them will be >fast enough.
