Using a Mac G4ppc as a wireless music player/hub?

Hi,

I probably don't know much more than you do about all the available options, but we can at least brainstorm together.

If you can plug your sound system directly into the computer and control it with a wireless keyboard, then you can achieve your play/pause/skip functionality with the spacebar and arrow keys from anywhere that the keyboard will reach.

Or there's Bluetooth speakers. A lot of these have pause/play and skip buttons. The caveat is that you can only connect to one Bluetooth device at a time, so unless you find a device that can split out into various speakers, you might only have one speaker.

Also, the G4 might need a USB Bluetooth adapter if it's not built in. This would apply to both of the above options.

The router option is probably more trouble than it's worth. I've set up a Mac Pro with a dedicated router before and controlled it via Screen Sharing on my MacBook Pro, and Air Display on my iPhone. It felt like a novelty gimmick, not something you'd actually want to do regularly. But it is possible at least with Intel Macs; I can't remember if PPC 10.4 supports screen sharing or not.

I don't know of any iOS solution that will interface with PowerPC hardware.

If you want to explore the router option further, I can detail how I set mine up, but from what I can tell, it sounds like a Bluetooth keyboard might be the absolute simplest way to accomplish what you're trying to do.

You could even add unlimited wireless speakers with a simple FM transmitter/receiver system, where you plug a transmitter into the computer's headphone jack and put as many receivers as you want on the same channel, with a speaker plugged into each one.

Hope this helps!
