You pretty much summed up everything there is to say.  I see someone replied 
off the list, but I'll add what I know, in any case.

As you noted, any regular data connection can be paired with others.  The 
limit is 7 connections, but you do have to remember that there's less than 
800kbps to go around on Bluetooth 1.2 and only a couple of megabits on 
Bluetooth 2.0.  I have managed a file transfer from my cellphone (only ever 
manages 25kB/s, ~200kbps) while talking on my bluetooth headset (not sure 
about bandwidth use for it) but I don't think I'd like to test anything else 
simultaneously.
