Speaking to its small and high quality implementations, Verisign gave a talk on how they used it for their high availability/performance servers. Rather than the usual throw more hardware redundancy at the problem, they went the other extreme and audited and understood every line of code in Lua so they could create a reliable system by eliminating bugs. And Wikipedia (Wikimedia) uses Lua for their multimedia scripting engine. Besides good performance, the implementation was good and small enough that it could be audited for security.
