Youtube video of you holding up or saying your BTC and telling your birth date.

This would not be proof enough to be exact but it could differentiate a 16 year old from a 50 year old.

Maybe will make a lot of money the first DAY or so.  Retargets intervals are every 2016 blocks not every 2 weeks.  So if hash rate rises 10x the week all this gear ships the network will retarget in 0.5 to 1.4 days.  So say 1 day @ $15 per day.  Max retarget is 400% so then it is maybe another 5 days @ $4 per day.  Then after second ratarget difficulty is now 10x as high so revenue is down to $1.50 a day..  So you might get $15+5x$4+24*$1.50 = $71 the first month and then $50 a month after that.  If more than 100TH/s are added you would get even less.

That assumes you get a unit delivered on day 1.  If you get a unit delivered on say day 6 you miss both retargets and start at $1.5 per day.

Note the numbers aren't intended to be exact obviously the exact difficulty, the amount of increased hashpower and BTC/USD rate are all unknown.  It is more intended to show that if network hashing power rises significantly the retargets will be very quick. 

Having trouble here.  I burnt up a PSU because I bought a shitty bargain one and ran 3 5850's with Reaper.  I have 2 computers. One with 3x 5850.  Other 2x 5850 and one 5870.  What power supply on newegg should I buy?  COST is a HUGE factor.  Hopefully single rail/under $100 would be great for both.  Should it be 850watts+ or more?  Is a $100 target viable for a power supply that could last possibly a year litecoin mining, or bitcoin mining for at least 6 months/whenever ASICs hit?

It probably contains 1.2g of unobtainium and will run until the 2nd coming autonomously!

This is funny. Every object in this Universe can be used as medium of exchange!

unclemantis, I do not think blakdawg's statement was intended to be taken personally.

He is merely illustrating the differences people have when it comes to weighing the value proposition that skilled and competent tax and legal service providers offer which is not a whole lot unlike insurance. It is a balancing act between (1) the cost of the service provider, (2) the probability of a negative occurrence happening and (3) the potential cost of that negative occurrence.

Those people that hire the tax and legal service providers are generally those that find an ounce of prevention is worth a pound of cure.

Personally, I have always been one to buy an ounce of prevention in the hopes of preventing a pound of cure. The last lawsuit I got out of we won on summary judgment with prejudice and the judge still did not give us any attorney's fees ($65,000). But tax and litigation is just part of the cost of doing business. Making money the legal way, and not having to worry about looking over your shoulder, is generally a lot easier and less stressful than doing it a shady way; just look at the Monex whistleblower example.

I was looking recently at someone do this at a tourist location in Venice: http://www.youtube.com/watch?v=5ko5RE2oh00

I instantly thought- how cool that would be to do for Bitcoin. Etch via Laser QR codes of bitcoin addresses and Private keys into the crystal. For example you could perhaps even do multiple layers of bitcoin addresses on on plane, and private keys on another, and using a special planer light source illuminate only one at a time. If your light source was super thin and planer, you could potentially store tens, hundreds or thousands of addresses in the crystal depending on the technical limits of the system.

Could make for an extremely cool "cold storage" system. One could image the sense of power from opening a safe deposite box to find only a crystal cube.

Of course, unless you do this at home- how do you provide a service and securely include the private key?

Yes, we certainly are. And so should everyone in the ASIC business, including Intel. If BFL's numbers are to be believed, our assertion is that they have discovered new manufacturing processes that are vastly more efficient than anything the semiconductor industry has seen before.
