It may be impossible to make a theoretically unbreakable device, but that doesn't mean it's practically breakable.
You say yourself that it might take 10,000 years to get the correct key, so if the useful life of the device is say 10 (or even 100) years, it is still practically unbreakable.
And if you can make a device that takes 10,000 years to bruteforce, you can make one that takes 10,000 universe lifetimes...
As long as the complete bittorrent data unit fits inside ONE packet, yes. If however the thing that describes the file it belongs to and the position in the file it goes in is relatively large, you're being quite wasteful. Assuming 1400 byte max packet data, 8 bytes of file position (i.e. files may be bigger than 4GiB), 4 bytes to give the index of a file, that's 1388 byte packets... 3094357 packets at least for 4GB, an extra 32MB.
If instead we can do 32KiB or 64KiB runs (reliably, i.e. sliding window makes sure of this before doing it), 131072 or 65536 packets, 1.5 megs or about 750k overhead, respectively. For a single user this difference is nothing; for the entire Internet, given the amount of bandwidth and possible traffic (hint: ISPs are complaining), taking it up even higher saves them a huge bundle on bandwidth.
But you have to also take into account the overhead of TCP's in-order delivery mechanism: UDP has 16 bytes less of header so you can squeeze more data in each IP packet. I imagine that in the end they would both come out to about the same.
An adequately sophisticated computer could do likewise if it had onboard both a turing machine (for instruction processing and for building formal reasoning systems) and a neural network (for recognizing objects and for seeing abstract similarities between unrelated objects and ideas).
Are you saying a turing machine cannot simulate a neural network?

It's easy for me to say "put Linux on a neat product!", but picking the right product, making it work, and convincing somebody to do it... well if I could provide a step by step of how to realistically pull that off, I'd deserve more than a +5.
You're almost there, it's
1. Pick the right product
2. Make it work
3. Convince somebody to do it
4. ???
5. Profit!
I've noticed that with my MacBook Pro. I get a slight tingling feeling when I use the 2-prong connector and sometimes with the 3-prong one, especially from the corners/edges of the case. Most other people can't feel it, but I eventually took a multimeter to it and found there was ~80V AC on the case.
"I was tired of North Korea's harsh penalties for being a citizen. That's why I moved to Iran!";)
The problem with that analogy is that Iran is a much better place to live than North Korea. No, the problem with that analogy is that it doesn't contain any cars.
Rubbish! The Amiga was a far superior machine to the IBM PC but Commodore/Escom/Gateway/Amiga Inc. did not have a single clue as to how to market it and expand it correctly. It was their total lack of incompetence that caused its death.
Hmmm I guess that explains how Microsoft did so well then.
Now, supposedly it just takes a few seconds. But is there a cookbook example, preferably for OSX, to routinely log into a WEP-enabled wireless network? Can it be done in a chicken-and-egg situation where it's impossible to download software? Where there's only a single machine available? Is it possible to do with no traffic on the wireless network? Try KisMAC. It can't do packet injection with the built-in WiFi (at least not on MacBook Pros, I don't know about others), so there needs to be a reasonable amount of traffic available to sniff.

You could get a cardboard cutout made of yourself to fool the rest of the office.
It'd probably be less painfull if you got it made of cardboard.

What the Hell? spreedsheets were the killer app for PC's period.
No need to get menstrual about it ;-)

oh wait...
Like on a 3G iPhone? Their pseudo-GPS using wireless access points gets pretty darn close. It usually pinpoints me within a building or two.
I thought the 3G iPhone had real GPS?
Really useful artificial intelligence is currently just 10 years away... just as it has been for the last 40 years!
...and will be for the next 40 years!
I'm surprised no one seems to have mentioned KittenAuth.
OK, it doesn't solve the pr0n hole, but otherwise it looks pretty hard to break.

It's more than that, 2^65025 / 2^41 = 2^64984, which is a LOT more than 9 billion billion years
Especially DHMO!

What, as opposed to rural cities?
