By my reading of the rules he can't. What you do at your own table is, as always, not something I care about.
Except that it is explicit in the book that a TM can thread a CF to twice his Resonance. This is from the book where Programs did not exceed Rating 6, as well. The end result is that a Technomancer can conceivably have a CF that he can thread up to 12+, should he care to risk the drain.

My understanding of this means that the end result of threading is the setting of a CF rating.
Above that on the same page. So there is a link between the CF rating (even after being threaded) and the program rating.
Yes, and No. A CF acts like a Program, but can have ratings equal to twice the resonance of the TM (Through Threading). You Threading allows you to exceed the rating fo the CF you have, or provide you a CF you do not have.
Emulation allows you to mimic a program (Specifically for Biowires and ActgiveSofts) such that you can then save it as a CF. But this is a Skill, not a "True" program CF, and thus cannot be further enhanced by Threading.
Purchasing such things as a Smartlink and Simrig allow you to emulate Hardware as well, and are bought as a CF, but these CF's cannot be further Threaded either, because there is no effect for having a Simrig or Smartlink running at a "Higher" capacity. They only do one thing.

As I read this last sentence, unless you houserule the existence of CFs for which there is no software, then CFs are limited to existing software and whatever the possible ratings of that software are. If, pre-war, you had software ratings in your game higher than that obtainable by players, I see no reason why technomancers couldn't thread it, but if software ratings were limited to that available to the players, that limitation also applied to technomancers.
As always, feel free to interpret differently, or, if you simply don't like it, declare it fluff.
There are already concrete rules for things that have no "Software", per se. The Smartlink and Simrig (and other related Hardware that the GM authorizes) are examples of such things.
CF's allow the explicit bypassing of the Program Ratings. That is exactly what Threading is designed to do. Of Course, as you say, you are always, feel free to interpret differently, or, if you simply don't like it, declare it fluff.
