In their own words

"SpoofCard offers the ability to change what someone sees on their caller ID display when they receive a phone call. Simply dial the toll free number and then your PIN. You'll then be prompted to enter the destination number followed by the phone number to appear on caller ID. It's that easy!"

	Why it might be a killer

SpoofCard could be great for both business and personal calls that you wish to remain private. It would be perfect for anyone who doesn't want their personal phone number exposed to avoid follow-up phone calls by an unwanted party, as well as for the adulterous partner who can't have his calls traced back to his affair partner's house phone. I think the fact that SpoofCard's services aren't free will keep mischievous sixth-graders from abusing its services, leaving SpoofCard to remain a largely professional service.

	Some questions

According to SpoofCard, its services are completely legal. However, there's always the possibility for abuse. In particular, the voice-changing feature is a bit sketchy; it's just begging for suspiciously motivated calls. Since there are already several services out there that block someone's caller ID from displaying your number in a much easier (and probably cheaper) fashion, I wonder if SpoofCard's extra features will have enough pull to make people pay for this service.
