Yeah, but in these use cases it's using a lot of traffic because the application of file transfer, and voice/video conversations use up a lot of bandwidth. If we take, for example, an application like Bitcoin, it uses a minimal amount of data transfer because all it's doing is coordinating transactions and mining. If take a simple use case like P2P text chat, would the bandwidth costs be all that bad compared to a cloud or client-server model?
