Obviously, if servers and load balancers don't support the same algorithm they will not work with each other. There's not much to do there.
However, if servers have mutually exclusive algorithm sets, there is no way for load balancers to have a common regime.
One way to solve this is to force servers to support everything. Another would be to extend the solution to Issue #8, taking a handful of bits to encode various configuration regimes.
