The Napster production server engineering team was just me for most of it. Early on there were two other engineers, but one left for management and the other to start a company. I'm personally not familiar with Erlang to know if it would have worked for us. A lot of our scaling was about being very efficient with memory (the whole thing ran on little Pentium 2 machines with 2 GB of RAM each and part of the protocol unfortunately relied on MD5 hashes of files for file transfer which took up most of the memory).
