Bluetooth inside LXC container?

[huawa]

Is there a way to get bluetooth working inside a LXC container?
On the host-system bluetooth is working correctly.
In the guest-system (Debian LXC) it is not accessible.

Doing a "hciconfig" on the HOST system returns:

hci0:Type: BR/EDR  Bus: USB
        BD Address: 20:33:A2:EF:22:45  ACL MTU: 1021:5  SCO MTU: 96:6
        DOWN
        RX bytes:683 acl:0 sco:0 events:46 errors:0
        TX bytes:817 acl:0 sco:0 commands:45 errors:0

Doing a "hciconfig" on the GUEST system returns:

Can't open HCI socket.: Address family not supported by protocol

I guess it is related to having different namespaces?
Any idea how to get this work?
