For what it's worth, on the multiple frontend issue (not s2 related)...
A board will appear with some or all of the following features before
you know it. Analogue PAL, DVB-T and DVB-S on a single bridge.
Personally, it's more logical to me two have two different frontends,
one for S and one for T. Anything else feels like a hack.
Analogue tends to take care of itself through v4l, this probably should
change longer term.
