Tvheadend

Hi,

I have a Wetek box(DVB-C tunner) with OE and TVHeadend backend and frontend installed.
I want install TVHeadend Client on kodi(android or Windows) and change TV channels from that, but this is just possible when I turn off TVheadend Client on Wetek.
My ideia is when a new TVHeadend Client try to connect to TVHeadend backend in Wetek, if there is another existing client connected then put them off.
Is this possible?
Or, other ideia is to sincronize current channel on Wetek for all connected TVHeadend Clients and when one client change channel this sincronize to Wetek and for other clients.

Thanks.
