 This is the dual of #25601.

 It would be a great feature if a client could be connected to multiple
 snowflake proxies at once, and split traffic across all of them. Like the
 [http://cacr.uwaterloo.ca/techreports/2013/cacr2013-16.pdf Conflux]
 proposal for Tor. It would be a hedge against getting assigned a single
 slow proxy.

 This would require interposing some kind of sequencing and reliability
 layer, with possible retransmissions.

 A potential benefit for privacy is that an individual snowflake proxy only
 sees a subset of a client's traffic flow.

 However, instantly making ''N'' WebRTC connections is a tell for traffic
 classification.
