Tvheadend

Hi,
I use the cardsharing via 3g usb modem. In the tab "CAs" I prescribe 2 ports on the same satellite (85.2), but the traffic consumed 2 megabytes per day. I do not watch TV thus tvheadend does not send a request for a key to the encoded channels, but traffic is 2 megabytes tvheadend consumes. I found out that traffic consumes CA client by sending a request to check the work of cardsharing server. In month tvheadend consumes 60 megabytes. If I watch TV, the more traffic consumed. But it would be possible to turn off or increase the time of the request thus reducing the traffic consumption.
So, can i hope for the emergence of new functionality on the frequency change request (see my version of the functional on the CA tab)?:
"Time interval"
a) if disabled, default request - as usual.
b) If enabled, the query frequency can be selected arbitrarily from 0 to 1000 seconds.
The name ("Time interval") and the maximum time interval may be modified by the developer. I just showed how I see the new functionality.

I think that is responsible for this CWC_KEEPALIVE_INTERVAL (https://github.com/tvheadend/tvheadend/blob/master/src/descrambler/cwc.c).
