Spam: Unsolicited Emails
Spim: Unsolicited Instant Messages
Joy. Now there's "Spit". Audio spam.
Got VoIP? You could well be stuffed.
Well, that's probably not true. There have been no documented cases of VoIP spam/spit yet, but taking a look at some figures here (leans over to some research), In 2003, there were only about 131,000 residential VoIP subscribers in the US, but by 2008 the level is projected to reach 17.5 million. Spam became widespread because there was a big enough target audience, and these numbers are untouched CREAM for spammers.
I don't know anyone in NZ who uses VoIP, but lets hope Qovia's patent is an international one.
