Compatible Bluetooth Connections

For the festival at my college, we are planning a quiz contest.
For the buzzer round, I thought of writing 2 applications for the android (we have several phones), one for the quiz master, and the other for the participants
Participants will be connected to the quiz master via bluetooth.

After reading the question, the quiz master clicks the button in his application, the button in the competitive applications will be turned on for X seconds. As soon as a participant clicks on his button, the application-master survey will blink the name of this participant.

My questions:

Is it possible to have several connections and receive parallel (or multiplexed) messages in bluetooth (something similar to select () in unix / c)?

If possible, where to look for all the examples? What problems will I experience when trying to develop this (I know that the reliability problem is here) and how to avoid them?

I tried this on laptops before and couldn't. But maybe I gave up very early. Please, help.

EDIT:
I abandoned the project (too many connections). I keep the question open, though.

Bluetooth supports piconets in which one (victorizer) can communicate with up to 7 slaves .

So, at the Bluetooth level, this should be doable. I am not the one who can say whether it is possible to implement with the Android Bluetooth API: s, however.

Have you read all the information available specifically for Android? http://developer.android.com/guide/topics/wireless/bluetooth.html

In addition: when I was in college, we did nothing according to the old style (paper and pencil), but with the plus, you should not have to worry about the expensive handsets in the hands of drunk college students !; -)
