The first barrier is that you need a secret key in order
to connect to the CableLabs certified recording hardware in
permissive mode. CableLabs will not issue such a key until
you've paid them $500,000 for them to certify that you have:

1/ made sufficient measures to prevent anyone else from
    gaining access to that key.
2/ ensured that the application can't be hacked to allow
    the end user to view the content in unapproved fashion.
3/ complied with a whole bunch of silly requirements that will
    add another $500,000 to the software development costs.

If you give me $1,000,000 + a reasonable profit today + I can
probably give you one system running MythTV that is CableLabs
certified in 2-3 years.

The barrier is not entirely insurmountable, but it is very
expensive and if I had that type of money to spend on MythTV
I'm pretty sure this isn't how I would spend it.
