nope, sorry. altho i would guess it could be done, in theory, if the right setup was done with the bluetooth stack of the tablet.

what i did was

1. use a a2dp headset with my phone to listen to music being played on the phone.

2. use the phone as the internet connection for the tablet.

3. use a bluetooth keyboard to type something on a page shown on the tablet.

so i had 3 bluetooth connections going at the same time, with the phone and the tablet both maintaining two each.

funny thing is that since then i have added a 3G phone, so if im using 3G for the data connection, i could potentially make and receive calls with the headset (one of the big things about 3G was its ability to handle voice and data at the same time, vs gsm that could only do one or the other).
