Not quite true: all the bytes must come through. The order is not  
important as bittorrent proven already.

Using jingle for file transfer makes sense from a provider  
perspective, regarding relay cost and speed. But for clients, I feel  
that we are reinventing the wheel (TCP in this case, and it's a big  
wheel), and that we are trying to solve a problem that does not need  
solving right now.

I'm all for using jingle for file transfer when it is deployed in  
large numbers and the VoIP part has been used for some time to  
stabilize the basic signaling protocols, but Jabber.org pushing a new  
file transfer mechanism just now its very bad for all of us.

SI has it's problems, but it is here now, and it's simpler to  
implement than jingle. jabber.org should recommend heavily the  
implementation and deployment of si-based file transfer. Then we  
would have a common protocol that all people can use.

If later a jingle "super-fast" protocol comes along cool, you'll just  
use it. But not having a common basic file transfer ASAP is hurting  
us all, me thinks.
