And at $400/hr you’d make that in less than three hours of work!

You don’t need to use matching drives for RAID. Capacity just needs to be greater than or equal to the original. And with drive capacity continually increasing, it’s not hard to do that.

Ack, slashdot fails. “6 cents per call”, etc.

Umm, no. Landlines do pay on a per-call basis. My landline billing is or was last I checked, something like “6 per call for the first hundred calls, 5 for calls 101–500, 4 for calls 501–1000, 7 per call after that. Long distance additional (and per-minute)” Even at best it’s “unlimited flat-rate service only for local calls” so you better hope the callee’s phone number happens to be local or you’ll be paying that per-minute fee (or using long-distance minutes if it’s billed at a flat rate) So yeah.

Not really. In your scenario above, and with “caller pays” billing, it simply means that (B) pays for the call instead of (A). This is true regardless of whether A and B are landlines or cell phones, assuming “caller pays”.

How does that make it free? It just changes which end pays for the call. Of course, one end may have a better plan that allows free calling in some circumstances, but them’s the breaks.

There are software DTMF generators, which should do the job assuming the GP can get the output over to the mic of the telephone in question somehow. A quick Google search turns up several results.

Salvia Divinorum != Cannabis Sativa. Also != saliva.

In what world is this? They’re dark purple or grey. Sometimes the optical drives are black, or some of the trim, but that’s about it.

You know, there are non-nuclear power plants.
