Yes, the code has support for this, but you need to enable an
undocumented variable in the config, whose name I don't remember at the
moment :-) as well as set a list of node hostnames and a load-balancing
algorithms (the two latter are documented). Search the nxserver code for
load balancing, you'll see the variable value being checked - it's all
capitals and underscores and contains the string LOAD_BALANCE i think.
