Narrowband signals like these aren't so hard to deal with and there's a long history of radio hacking. The ARRL, QST and thousands of "radio hackers" made up the HAM community for decades.
The frequencies used by the cable companies aren't that high either - designing a board for a modern Intel processor is far harder. The thing that made these frequencies hard for CATV companies is that the signals were so wideband. A typical coaxial cable carries signals between 54 and 1000 MHz ... you're burning a lot of bias current to keep the system linear (thus avoiding distortion).

Lots of people can do RF design. Lots of people can do DSP. Lots of people can do HDL. Lots of people can do C. And there are a fair number of people who could do all of the above... but 99% of them are too chicken to try. That's what earns my respect, more than anything else.
