Of course, streaming media protocols like RTP or Skype are bandwidth-
adaptive, lossy, and meant for applications that are *not* serious bulk
transfer. Makes the design *much* simpler, with much less need for trust
or coordination between nodes.
There's likely a way to make a PtP-friendly protocol that somehow serves
both RT/streaming and bulk uses. I suspect you'd end up with something
like XBox LIVE - various application-specific protocols over a peer-to-peer
VPN over UDP.
