True. But the eavesdropper needs to have physical access to the
appropriate cable at least once, while email can be hacked remotely.

Come on. Of course every phone line can be tapped (except if you have
one of those 007-gadgets where you have to say "scramble!" before
starting to speak, and the whole conversation is encrypted even if the
other party uses a standard phone), but this is only likely in the
event someone has a personal grudge against you or the other party in
the phone conversation. Sure, government agencies do that all the
time, but how likely is that that the average hacker taps a phone/fax
line? Do you keep a gun under your mattress yet?

For the technology yes. However, I would believe that the number of
hackers connecting their fax machines (or software equivalent) to
other people's phone/fax lines is less than those intercepting IP
traffic remotely. That's just a guess, I have no figures.

I am also still waiting for the headline "Credit Card Details Stolen
by Gang who Connected Fax Machines to Vendors' Fax Lines". If you say
this has happened more often that with credit card details sent by
unencrypted emails or via unsecured websites, or has happened at all,
I would be amazed by "someone's" ability to keep it out of the press.
A new conspiracy theory is in the making... ;-)
