We don't want to send data (base64 encoded) through the server unless it is the last resort.
This is practically identical to ibb. Best is to stay with p2p transports as far as possible.
Even proxied bytestreams are better than base64 encoded data.

Most of this will be solved by jingle transports, eventually.
