    At some point, they're going to start using tamper resistant hardware. Good luck mod-chipping that.

    They can't possibly achieve that way. Nothing is 100% tamper-resistant. Doing this to the entire market will create rather huge demand for "tampered" devices, which is a decent incentive for black market. Tamper resistance is also rather expensive; consumer devices are unlikely to use that all - and look at the "I ported Linux on Gameboy" crowd, it's fairly likely at least some devices will be modifiable in the required way. You can make a decent computer from off-the-shelf chips, even "mere" microcontrollers have interesting power now, see eg. ATMega family; the market with general-purpose chips would have to be tightly controlled as well, at which point all the small and middle-sized development-doing companies (or dependent on custom development) start screaming bloody murder, and black market inevitably appears. (Or the "legal" systems will be flexible enough to fulfill any needs - then they are likely to be flexible enough to run just about anything on them - including an emulator of a non-TCPA computer.) The countries that deploy this measure effectively kill most of their R&D, which will cause mighty cheer in the "underdeveloped" nations.

    The only hole you can actually count on, is digital-to-analogue-to-digital conversion, to get data out of your "trusted" box and into an ordinary computer. That might be fine for ebook pirates, but it's going to be one hell of a PITA for daily life.

    Multiple options exist. The D/A-A/D conversion with audio coupling is a bit extreme, however many other possibilities exist; odd kinds of network protocols, serial link (if present), high-speed lab equipment. You can even bump the audio link speed up by using multiple channels and higher samplerates; I think the successor of AC'97 codec should go up to 192 kHz on 24 bits and 5+ channels, even a rather ineffective data encoding scheme could get quite fast here, presuming the setup is local and the cables are high-quality. Many people here derided it as an overkill - for audio maybe, for unintended purposes it may get pretty handy. Also don't forget various options for video - from digital cameras to DV camcorders to anything exotic the future may bring.

    Rather than planning to spend tens or hundreds of hours on work-arounds when this happens, it would make sense to donate tens or hundreds of hours of your wages to the EFF or similar organisations which are working to prevent this problem from prevailing in the first place.

    This presumes two things: a) the belief that the organizations will be effective and successful, preventing the problem instead of just slightly delaying it, b) that the money from the wages will have more worth in the global scheme than development of purely technical politics-independent countermeasures, and b.1) that the technician in question is so swamped with paid-for work that he can pick as he pleases between working for money to donate and working on a countermeasures project - which was maybe true in the US at the peak of the dot-com boom, but may not be always an available choice for an underemployed technician, a student, or somebody in a low-dollar-wage country (eg. East Europe or India/China, and the most of the world in general, if you look outside of US/EU/Japan).

    Whatever approach you think is the best, do it. If we can survive, it's by diversity of approaches - being it donations or tinkering. Do what you believe will have the most effect, whatever it is.

    Your 'force people to use iTunes on all their machines' argument is a bit specious, since it's free...

    "Free" in this meaning sadly doesn't mean "works on every machine and every OS". So modifications may be necessary, including but not limited to reverse-engineering the protocol.

    Their are no legitimate reasons to hijack an iTunes stream, for any reason.

    Compatibility. Ease of use. Streaming to an Ethernet-connected device just built for that purpose. With a bit of creativity, you can see a plenty of reasons on a glance.

    There is always a workaround. It may be "chipping" the motherboard - possibly will be illegal, but who cares. It may be even running a pair of computers, using the TCPA one as an access device for the non-TCPA one. Even in the VERY worst case, we can return to the age of BBS systems, acoustically coupling non-TCPA computers with the TCPA ones, then communicating with audio-encoded data over VoIP phone clients. Would be rather slow, but even that would be enough for sharing an AES256 key and arranging sending an encrypted DVD-R by mail or by a courier.

    There is almost always a solution. In virtually all the other cases, there is at least a workaround.

    Make an import/export filter set that will heavily depend on NetPBM. Then they can "outsource" all the JPEG-related functions to the NetPBM package, and be clear like a lily themselves. The infringement itself is then committed by the end-users themselves, who set the import filters to use the convertors in question - which is too many people with too low value and practically zero chance to be caught. Of course this shifts the heat to NetPBM, but due to the extreme modularity of the package and wide availability of the modules, getting it out of distribution is fairly impossible, even if all the US-based developers would give their hands away from the jpegtopnm program.

Holders of other pieces are online and offshore. The goons would have to get even the m-1 of others to cooperate - which they may not have legal jurisdiction over.

    Then there is the outsourcing way. If the US workforce is so expensive, let's go elsewhere. Including the "knowledge workers" and the developers. Giving away your crown jewels, for some ephemeral profits.
