supporting both btgatt-client and btgatt-server in application

hi all,
We have an application that should support both btgatt-client and
btgatt-server (connecting to different devices for different
workflows), using bluez.

1. Should I create a single mainloop that will be used by both or
should I create two different mainloop_run? (thought of have porting
the mainloop code to c++ and change it to be class element)

2. Regarding the btgatt-client, how can I initiate a disconnect? (I
looked in the btgatt-client.c test application and did not see an
initiation of disconnect).

thanks in advance! (hope I sent the message to right mailing list.. )
