I know for certain that adding a userland API tuner/demod interface to 
the kernel, allowing non-caring opportunistic silicon or board vendors 
to developer closed source proprietary drivers, will have a negative 
effect on the community and we'd set back linuxtv 3-5 years.

I know for certain that it would happen. Trust me.

I've told you this countless times and you're not hearing me.

Hauppauge have some leverage with Conexant and NXP to release public 
datasheets. If they just have to release a demod.so (or similar) 
loadable, they'll defer to the board vendors and we'll see the certain 
board vendors 'locking other board vendors' out of their drivers. We'll 
see embedded firmware, not shared between drivers.

Except, it won't stop at demod.so. It will extend into unfixable bugs 
for VendorB's board, because VendorA doesn't want to release a new 
demod.so, and VendorB has no linux resources. What happens next? For 
financial reasons - demod.so will begin to include checks to see if 
specific PCI or USB devices are present in the system, and will fail to 
work properly (if at all) when they're not being used with the preferred 
products.

Read my lips: For commercial reasons, this enables driver components 
that only work if specific boards are present.
