Load Balancing With Riak Ruby Client

This is one thing I desperately want to refactor. The Ruby client still contains some things that reflect my earlier, less astute understanding of how a Riak client should behave and doesn't include obvious things like retrying requests (possibly on other nodes), conflict resolution strategies, and mutators.
In the past, I have recommended that users put a lightweight load-balancer (e.g. haproxy, pound) between their application and Riak, and simply have the app connect to the locally-running instance of the LB. I realize this is not a great solution, but it also avoids a little NIH for now.

Would I create a Riak::Client for each host, and then just randomize the selection of those for a given call? Do the clients contain any state that would make this a bad idea? Or is there a better way to do this?
