For every attempt at control, there will be 10 ways to circumvent it (or more). Look what happened with the telephone industry. As soon as reasonably high speed internet came about, internet telephony jumped right in. We have thousands of phone numbers in our call center, including a large supply of 800#s, and only a handful of land lines, primarily used for 911 service, alarm system, and a couple of old fashioned backup fax machines.

And I have stretched beyond the limits of our telecom system, which uses IP phones, and gone to a phoneless phone. Just my USB headset and a free software client and I can use the work phone system to call anywhere.
