There does need to be a standardized reliable stream layer on top of
UDP type Jingle connections.

In Google Talk we have one which you can see in the libjingle source
code, called PseudoTcp.

Before standardizing, as a point of comparison, some of the dedicated
file sharing clients also have "reliable stream on top of UDP"
implementations. The topic is complicated; I propose the design of
choice optimize for reliability, throughput, and simplicity, in that
order.
