If something like that went to trial you need witnesses in person along with expert witnesses who can explain Bitcoin. Then, even if you get a judgment, you still need to collect it. http://en.wikipedia.org/wiki/Digital_evidence

It's an agreement between bASIC and the paying customer. So, what matters most is the value of the product (USD) offered when the contract agreement was made (i.e. when you paid him whatever), not what you gave bASIC. For example, bASIC could have asked for tomatoes or a thimble full of salt, and promised to deliver the product (based in USD). If you gave him the tomatoes (or salt), and he failed to deliver the product, then he broke the contract and would owe you something. If you took him to court and won, you would be awarded the value of the promised exchange in USD. Bitcoin shouldn't need to be explained for a case to be effective. It seems the only explanation that might be made would be to appease a judge's side curiosity - not to make the case solid.
Maybe I missed your point though. Sorry. And you might be right, since there will need to be proof of delivering bitcoins to bASIC. That will be figured out if/when it comes to it, and shouldn't be too difficult to prove. There are a couple people in the area that might be able to do this, or maybe someone that can travel there. Thanks for the input on that.
