Email isn't used in pharmacies. I've worked with them. They're called e-scripts for short. They're a secure, encrypted method by which doctors can send prescriptions into pharmacies without a hand-filled Rx sheet. You can't e-scribe controlled drugs anyway. They're mostly used for maintenance medications. They're sooo much faster. With fax, you have to scan in the script anyway for a visual record of the prescription, then transfer all of the dosage, drug name, sig, doctor, patient info by hand. With e-scribe, they're already filled in for you, as well as the image of the prescription. The pharmacist just has to double-check to make sure it's correctly done from the doc. Saves so much time that a full-timer was cut from the payroll at our store...multiply that by the 3000 rite aid stores...and that saves a lot of labor hour.
Your extremist view that 'drugs for all' will occur is a little inflated.
Fax is slow, very bandwidth intensive, and not reliable (dropped calls, no pickups, busy signals) compared to net software. However, I can see how the visual records needing to be maintained is imperative to business. It still needs to die.
Vonage, however, advertises the fax line as part of their service, so I'm guessing they have at least a little bit of overhead put towards development of a more solid service than MajicJack would.
