There are a few features that you need to understand in order to utilize multipoint communication:
1. Bluetooth do support star topology, which is 1 master to multiple slave connection. But this topology depends a lot on the master device, as slave will only wait for connection. We do not know whether the Bluetooth on your computer support that and if it supports, will the BlueBee support it? This you have to verify.
2. Though is multipoint connection, but will it be multipoint communication simultaneously? Let's say, 3 BlueBees are connected to your computer Bluetooth (I am not sure whether it can be done), BlueBee 1 send data to computer, and BlueBee 2 send data at the same time. Assuming the master Bluetooth handle the traffic and send to computer application, but how can your application (say the hyperterminal) know which message is from which BlueBee? This is different from WiFi communication which uses TCP/IP which utilize IP address, socket and port to separate the message from different devices.
We did carry a model of Bluetooth module that supports multipoint connection a few years ago, but it is obsolete because not too many uses it. Most of Bluetooth application is point to point communication such as mouse, keyboard, headset, remote, etc.
