We don't know yet where the boundary will be. I don't believe anyone other than MS has the rights on a PC. And that requires a CableLabs / OpenCable membership that may be beyond our means.
To support digital cable content, two things need to be done:
1. Implement the DRI
2. Implement a supported DRM mechanism
The DRI spec is freely available, and JRiver has done this already. As far as (2) there is actually no approval required from CableLabs, as long as you implement an approved DRM mechanism that the tuner also supports. The only 3 DRM mechanisms currently approved are WM-DRM, Helix, and DTCP-IP. Approval can be requested for other schemes, but that wouldn't typically gain much.
I'm not sure what the costs are for Helix, but it's basically dead (neither the InfiniTV, nor HDHR Prime supports it, and as far as I'm aware there is no real-world application of it even outside of OCURs). From what I remember last time I looked into this, it looked like the costs for WM-DRM approval were about $15,000, and the costs were similar for DTCP-IP. Not pocket change, but not outside the reach of most commercial software. Just to reiterate, this approval/implementation has no dependency on CableLabs - pick a supported DRM, get keys from the DRM provider, and you're set.

See above - that's a bit of an oversimplification.
