Is IM That Big Of A Threat?

In response to S.M. Schrama’s post on IM Forms A Security Risk To Companies I too believe that, IM should not be stopped on a corporate network. I think the company in question should definitely put together a list of guidelines for using an IM protocol on a corporate network but it shouldn’t be banned. If Pownce is a sign of the future in instant messaging, I don’t think we will have to worry about malicious code attacks via the IM protocol.
