A few days ago we heard a Skype representative t mention that it was “technically possible” to bring their VOIP service to the Nintendo DSi. Nintendo was quick to respond,with their normal response:

“We have no plans to release a Skype application for Nintendo DS or DSi,”

This is a normal “no comment” answer by Nintendo. It would be a wast for Nintendo not to have some-type of VOIP service on the DSi, skype, or their own thing.
