Plans are discussed to transition to a dedicated ISDN setup using AAC codecs to improve audio quality and reduce buffering issues. One host has already installed ISDN capabilities at a property in San Francisco to facilitate this change.

Skype Latency and ISDN Connection Technical Comparison

The hosts compare the technical performance of Skype versus ISDN for remote broadcasting. Adam Curry notes that ISDN provides a 60-millisecond delay due to dedicated circuits, whereas Skype typically has a 600-millisecond latency. John C. Dvorak mentions his recent Comcast speed boost to 16 Mbps down and 3 Mbps up, though he notes performance drops when connecting to international servers in England.
