Hi Marcel,
>> I've inquired with Aircable and it appears their Bluetooth Chip can handle 7 active connections and 128 parked connections. The comment at  http://osdir.com/ml/linux.bluez.devel/2003-07/msg00110.html also suggests that the CSR chip is capable of handling more than 7 connections overall.

You're right we're not building the chips, almost no one can do it, not 
every company can afford the money for this. We're just using BlueCore 4 
from CSR for the dongle Klaus is talking about.

According to CSR the chip it self should be available to support park 
mode, but I agree with you, I doubt they tested this in a real 
environment. I think that for bluetooth uses 7 connections is quite 
enough, I can't imagine when you would need more, the only scenario I 
can think off is real time sensors networks.

I agree.
