Here in UT they use a couple 1960s-era Howitzers for avalanche control in Little Cottonwood Canyon. They once loaded a shell with too much gunpowder and left a crater in someone's back yard 10-15 miles away.
I'll be looking at alternatives after receiving the friendly "We reviewed your account and determined that there's a relatively higher than average risk of future transaction issues" email that states they'll be holding my money for 21 days...
I have never made a claim. I have never had a claim filed against me. My account receives maybe $500/year, tops. I send $500/year, tops. HUDGE risk of transaction issues.
I think it's safe to say that for most businesses, while PayPal may only get you access to 80% of potential customers, Bitcoin gets you less than 1%.
Until Bitcoin is an established process, offering it means that you have to evangelize it. That means you are suddenly in the position of trying to sell both a service and a currency to a customer. That's more risk than most merchants want to take.
I did consider using it, I have a business with a fairly technical audience, but for now, I have to wait until the legal issues (whether only perceived or actually true) are worked out.
I recall years ago sitting in the LAX UA red carpet club listening to a portable cd player (yup, long ago). My music cut out, and thru my cd player, that didn't even have a radio as I recall, I was listening to the pilot pulling into the gate outside the window communicating with the ground crews over his headset.
Now, as I understand it, that lovely FCC stamp on the back of our electronics means the device must accept any interference received since it's a consumer product... but I'd also hate for my pilots to unexpectedly get my co-passenger's latest dubstep mix opposed to the air traffic controller during takeoff.
For the record: I'm the guy that intentionally leaves his phone on, in airplane mode, idling. I think this is good enough.
