Can this be plugged into a DDR2 DIMM and allow host Pi communication (with an appropriate kernel driver)?
The article says: > But don’t go plugging the Compute Module into your laptop – the pins assignments aren’t even remotely the same! So the answer is "no."
Do you think they've fused it so it doesn't short out and trash any board you put it into by mistake?
I've searched online, and I think the boards that the SODIMM modules are plugged-in to are called "base-boards" or "carrier-boards". In general, are these kinds of boards generic in nature, so that you can mix-and-match modules with different carrier-boards, as long as they all use the SODIMM package?
Looks really cool but I'm slightly disappointed to see that when buying these Compute Modules in bulk they still each cost about the same as a single full Raspberry Pi (Version A). The Compute Modules do have 4gb of built in flash that the Version A doesn't have though.
It looks like the module plus the I/O board costs $30 in large quantities. So aren't you really getting pretty much the same deal? I'm sure the modules alone will be cheaper.
"...the Compute Module will be available to buy separately, with a unit cost of around $30 in batches of 100"
So for many distributed computations in my field (pretty much anything that isn't embarrassingly parallel [0]), the limiting factor is often network communication -- how quickly nodes can send messages to each other. Even as just a toy, putting an affordable arm chip with a serious interconnect would be a really big deal. This is a great step closer. [0] http://en.wikipedia.org/wiki/Embarrassingly_parallel
The Calxeda ECX-1000/2000 would have been ideal for you then - 4x10GbE interconnects with a quad core A9/A15. Shame they went under - but there are alternatives from Marvell, Applied Micro and others. Look for ARM server chipsets and you'll usually find a good fabric attached.
It's about time they put some FLASH on-board. SD card has proven time and time again an unreliable medium. You never know if the device would boot up after a "dirty shutdown"
My understanding is eMMC flash memory is an SD card soldered onto a board, so if anything that problem could be worse without the advantage of a removable card

You will also find a large price tag. And probably inability to actually buy one alas.
The price is getting better but it's still in the "I used my pi for the project" vs the "I used a pi..." range. Things get interesting when a general purpose Linux computer reaches disposable pricing where you just pull a new one from the bin for each project. This feels like about $20usd or less to me.
So what happens to all that e-waste when you throw out an old computer board because you don't feel like wiping it?

Sounds like doing this will let out the magic smoke in a hurry. Do you think they've fused it so it doesn't short out and trash any board you put it into by mistake?
That said, if the Pi foundation can arrange for all the I/O to come out of reset in a hi-Z state, then there's a chance they could arrange the rest of the pins to avoid damage.
But would it be worth the effort? Given how hard it is to access most sodimm sockets, mistakes seem rather unlikely.
