did you consider haproxy?

In the cases I use this setup, HAProxy won't fit, since I route based on URL values. I do have HAProxy in front of my nginx machines though.

I actually use this exact set of software.

etcd -> confd -> HAProxy

It works great. I can dynamically route incoming traffic to groups of endpoints based on hostname.
