That will work great, until someone cuts the phone and cable lines to your house and your modem goes dead.
When I used to work on security systems we would bring along a shovel for installs. We would bury the phone line and move the phone box inside to the basement. Made it inconvenient for the home owners if they needed changes to their service (they would have to be home to let the phone guy in), but gave them a heck of a lot more security.
For my own place I put up a dummy box with some wires running into it. If they cut the wire it set off the alarm.
The Flash updater annoyed me the last time I ran it. The last update I applied snuck some Mcafee software on to my machine.
The flash updater now has the checkbox checked by default for mcafee security scan plus, and they moved the checkbox so you don't notice it when you are glancing at the installer.
Would some of the credit card companies go for something like this? I would guess they like having a piece of plastic in your wallet that you might look at on a fairly constant basis. Free advertising and a reminder to charge more on card XYZ.
I once read that is the reason that credit cards have a 2 or 3 year expiration date. They could last longer and they know they could save money shipping and producing, but the card refresh is a chance to get the card in front of you again in the hopes that you will use it more.
