So, it's entirely possible that such products are finished by one or more of the add-in PPC card companies, but they're too frightened of releasing them at the moment.

This could be a lie to cover for the fact that he's still not done yet, or it could be the truth-any company releasing such a product, which could presumably let a PC run anything that would run on an old-model iMac, would surely incur the wrath of Apple Legal. He was supposed to show this creation at Macworld Tokyo, but claims that the company which contracted with him was not ready to show it.

Jim Drew of Microcode Solutions (whose website only says "new website coming soon" right now) was contacted by one of the manufacturers of PPC add-in upgrade cards for Macs, and contracted to write an emulator which would emulate the hardware of an (old) iMac while using one of their PPC processors on a card to run the actual PPC software, such as Mac OS 9. This, of course, makes the use of G4 and when available G5 processors, possible, if one uses an add-in card. There are even a couple of whole-computer-on-a-PCI-card hardware firewalls available I don't know offhand if any are PPC, but that may be. These cards have been available for a long time in PCI form factors, though not yet used for PPC/Mac "emulation" most are sold as "processor upgrades" for older Macs, and some are sold on the high-end for PCI backplane machines, and some are add-in cards for extra processing power that come with plug-ins allowing Photoshop to use the extra processors and SDKs to develop support for other apps to use the extra horsepower.
Then, emulate the rest of the hardware on a given PPC Mac using some "glue" software. Instead, one could use a real PPC processor on an add-in card, maybe even with its own system RAM to increase speed. This is why I think the best way to get PPC support on regular commodity PCs is by not emulating the CPU at all. This is a hard way to work, from what programmers trying to produce PPC emulations tell me. In any event, while a usable G3 emulation is very possible, a usable G4 emulation will be impossible for many years thanks to the nice 128-bit Altivec unit. To even have a chance at being useful, you'd have to go the route of using a JIT compiler to dynamically translate PPC ops to x86 ops, and even then you're obviously paying a big speed penalty. You *can't* just map PPC registers to x86 registers like you can when emulating many lesser CPUs-*way* too many on the PPC, embarrassingly too few on x86. There are many reasons why PPC emulation on x86 is difficult, and why the resulting emulators have probably always been too embarrassingly slow for their creators to make and release a finished emulator.

There's no PPC emulation going on, really, with apps like SheepShaver the PPC chip itself is used, not a full emulation ofn the chip. First of all, the "emulators" you speak of for PPC machines aren't really emulators at all, they use the PPC processor natively, just allowing a MacOS that could run on that machine anyway, to run simultaneously under BeOS or Linux.
