Comment(by smcv):

 I don't think the Telepathy spec means the same thing you do by "one-to-
 one tubes", so retitling to avoid confusion. Please follow up if I'm wrong
 about the meaning of this bug.

 I'm assuming that this bug is a request for improvements to stream tubes.
 Instead of using D-Bus tubes, activities can choose to use TCP-ish stream
 tubes, in which one participant "exports" a listening (server) socket and
 everyone else can connect to it. Currently Gabble implements this, but
 Salut doesn't (#4241). The improvement represented by this bug is to use a
 direct TCP connection between participants if possible, instead of sending
 the data through the server.

 Possible implementation A:

 1. Implement OOB (out of band) bytestreams in Gabble

 2. Implement a fallback mechanism by which OOB is used if possible, and
 IBB (the current in-band bytestreams) are used otherwise - Rob thinks Psi
 has implemented a suitable technique for file transfer, so this needs
 researching

 Possible implementation B:

 1. Implement pseudo-TCP over UDP using Jingle and libnice

 2. Implement a Stream Initiation mechanism using this pseudo-TCP
