Client side load balancing across a universe of 20+ disparate nodes sounds unnecessary. Why is 20+ better than just giving out 5 random members of the universe for your use-case?
Is this HTTP/S? SNMP? Something bespoke? Why doesn't the client already know where all the servers are? How far away are the servers from the client? Can you put code that lives in the client, or is this existing client software you're trying to trick into supporting client-side load balancing?
Also, and only slightly related: Do you have a different definition of "use-case" than me that involves being as vague as you possibly can?
