Tvheadend

Hi,

I am going to setup a TV configuration for my son. It'll be based around XBMC with either the PVR branch or access via HTSP.
I was looking into the possibility to restrict some TV channels to be not accessible for that TV but I don't see the possibility to do so.

I see that different users can be configured but if I enable streaming every channel can be accessed, right?

Are there any plans to implement such a feature?

Thanks
Markus
