to keep it as simple as possible seems to me currently the best.

This way it should be less work to make it flow later with multiproto or
any other suitable for all solution coming in, instead everybody now
starts working on his own solution to make it more user friendly.

We have some dual frontend cards on the saa7134 driver and it is fairly
easy to deal with them.

Even the Medion Quad CTX944 with two saa7131e, two tda8275ac1 hybrid
DVB-T and analog TV tuners, two tda10046a for DVB-T and on the DVB-S
side two tda8263 and two tda10086 is fairly easy to handle.

The shared dual isl6405 LNB supply has some issues with the second DVB-S
frontend voltage settings, but this is the same on the m$ drivers and
out of range for these questions currently.

My two cents.

Cheers,
Hermann
