to from a single computer so that, for example, a person carrying a Bluetooth speaker could be paged or provided with dedicated music? In what language could the programming be done and what devices are needed? Best choice for greater distance than Bluetooth?

Sorry, dhvrm, but you missed the point of my question. I knew that two or more were possible as people are doing GPS and earphone. My question is: how does a programmer control where the sound goes. If there are two Bluetooth devices validated - say an earphone on Sally and a speaker in the kitchen, how do I send a voice message to just the speaker or just to Sally? Not streaming different stuff all the time but finding them and identifying them for transmission.

Blue Tooth is required because of a program using Bluetooth accessing a GPS receiver. WiFi would be nice if a choice was available.

Bluetooth doesn't care what it carries. The only question is how much bandwidth it has available.
If what you're asking is if you can transmit multiple signals via a single Bluetooth transmitter, the answer is yes.
Since Bluetooth is a device-to-device protocol, you simply need to know what device you want to connect and what information you want to send to it.
Bluetooth works fundamentally the same as an Internet Wi-Fi transmitter (a wireless router), just at lower power, a different frequency and less bandwidth (under 1 Mbps, vs 100 / 1000 Mbps for WiFi).
In other words, Bluetooth can connect to multiple devices and, depending on the version, do so anonymously or based on an electronic signature from a connected device; it just doesn't have much bandwidth, and streaming audio of any acceptable quality is probably going to need about 500 kbps, so you'll run out of bandwidth in a hurry.
A better solution is WiFi, due to the fact it has so much more bandwidth.
UPDATE:
If you read the Bluetooth spec, or even used a Bluetooth headphone for your cell phone, you'd know that each device carries an identifier and some keycode. That's how it knows.
Bluetooth can also handle anonymous devices.
Simply put, with an anonymous device, if it can connect and understand the signal it's getting, it can process the signal.

It would be nice to have a calm gentle ring like the ones at the place where I bank. Those harsh one stink and get on your nerves. I'm not
"in to" phones. Don't like to talk to machines or talk on them. Do like to write emails.
