I'm still using Lua on embedded Linux devices, and in fact completed a project last year that was deemed impossible by the Java devs, but easily within our memory/time budget as a Lua group. The success of that embedded Lua project converted a large number of Java diehards into Lua accolytes... Folks who sniff at putting a scripted/interpreted language into an embedded environment really need to think twice with Lua. It is fast, tight and highly performant - and if you bundle it along with LuaJIT and Turbo.lua, it'll give you the best of all worlds - aynsc i/o, coroutines, very, very fast performance and a great execution environment upon which to build truly useful apps.
