Is video conference calling on a iphone really a cost cutting way to meet?

Apple have been mulling a new in-house developed video calling software (ichat for iphones) to add to their functional programmes on the iphone. Various conference programmes exist already with Cisco (document and chat via iphone) services being one of the biggest but I am wondering whether this see this as a back door into enterprise sales. Mac enterprise share in Europe stands at between 2 and 3% and only a little higher in the US. But with any non-essential travel cut from most companies expenditure budgets I am wondering that if this future iphone leap would not be a home run for Apple.

But then again maybe not so fast as you would need a new iphone pro handset to allow you to have video in out capabilities wouldn't you ? And unless you are in a wifi zone, the cost of talking over a 3G roaming network- wouldn't that be astronomical ?
