FYI: "redirect" is the wrong word, has a meaning in HTTP completely
different from what you are talking about.

Peers are for message *routing*.

That is possible.

However, what do you want to happen when that users dedicated peer is
unavailable?
 Stop all access for them?

 Failover to going "DIRECT" instead of through the peer?

 Use some other peer, and if so which one and based on what criteria?

Are you wanting to keep this behaviour?

You can select a group of peers that each user has access to and apply
round-robin to them. However, any peer that is used by more than one
user will have its RR calculation implemented by *both* to prevent overuse.
 So the RR behaviour will not be easily visible. Selected peer (single
only) will be whichever one the user is allowed to access *and*
currently had least traffic going there.
