Kamailio Dispatcher Discovery Service with NodeJS and Etcd

An interesting resource for those relying on NodeJS for various needs and using Kamailio as load balancer in front of Asterisk or eventually other SIP systems (Freswitch, media servers, PSTN gateways, etc…):
Practically, this tool can be run along side with Kamailio and each SIP system (e.g., Asterisk), usingEtcd as communication channel to publish what SIP systems are available. Based on this information, the tool instance next to Kamailio is generating the dispatcher.list and instructs Kamailio to reload that file.
Etcd is a highly-available key value store for shared configuration and service discovery developed as part of CoreOS project.
