Lighten up. Obviously if he had a solution for you, he would have told you about it. Even if he hadn't questioned why you would want it, it not like his post would have been any more useful. It is perfectly acceptable to question why someone would need something if there might be a simple alternative.
Anyways, as of right now, it is impossible, and the odds of anyone doing it are slim to none, for a number of reasons.
1. It would be a huuuuge job. There are an immense number of obstacles to overcome, in many areas that have never been previously tread upon. Creating an extra Internet connection type would involve modifying the very framework of the firmware.. Plus, Apple has the iPod's USB connection locked down pretty tight. Ever wonder why everybody uses SSH to access their mobile files instead of harnessing the superior bandwidth of the USB cable?
2. Most people wouldn't have a use for it; this goes double for big-shot hackers. Most places that have computers also have wifi access. A few exceptions are not enough incentive for a hacker to spend months trying to figure it out.
Basically, the effort-to-payoff ratio is incredibly low, so I would never expect to see it happen. Ever. Sorry to crush your hopes. :/
Now, instead of going and whining to hackers who slave away years of their lives to give you free software in hopes that their ungrateful users will at least give them a "thank you" or a small donation, as aforementioned, the simplest solution would be to go out and grab a USB Wifi dongle. You can probably find one for pretty cheap, and it will easily let you piggyback your PC's internet connection, and you get the added benefit of being cord-free. If you ever feel daring, you could consider making the upgrade to the iPhone.
