From spam to spit

You didn't really think that VoIP would free us from telemarketers, did you?

New Scientist reports:

A new plague of unwanted messages threatens internet users, according to a US company. Spam and spim - spam by instant messenger – are about to be joined by "spit" - spam over internet telephony. Qovia, based in Frederick, Maryland, have recently filed two patent applications for technology to thwart spit.

There aren't any documented incidents of "spit" to date, but one security expert says that's simply because there aren't enough VoIP users yet to make it worthwhile.
