There are tuner cards with Linux drivers.  The hardware has room for
improvement, as do the drivers.  :-(

There are analog-only tuner cards with BSD drivers.

There are analog&digital tuner cards and USB boxes with BSD drivers currently
under development.  I'm watching this, and may try the USB version (machine has
no more slots) once the driver is ready.

The current hardware has room for improvement.  Better interference rejection,
(start with better shielding and better filtering) better multipath rejection, 
etc.

Developers have trouble getting documentation for the chips.

A 6th generation tuner that is significantly better than the 5th generation
devices and has good documentation would be very popular.  Many people are
having reception problems with the 4th and 5th generation tuners.  Not just
OTA reception either, some users have trouble with cable.

Testing the prototype would be non-trivial.  Different signal levels, a wide
variety of interference, a wide variety of static and dynamic multipath 
ensembles,
etc.

Another candidate for the 2nd chip would be OGC2 = OGC1 + onchip video decoding,
since it doesn't look like decoding is going to make it into OGC1.
