Looking at this more closely, it seems that what mobdebug does in Lua we can directly do in C++ through the Lua C API : http://www.lua.org/manual/5.1/index.html#index
MobDebug registers a debug_hook() in Lua and we can register a C function through : http://www.lua.org/manual/5.1/manual.html#lua_Hook
That would allow us to have a debugger integrated into Ctrlr itself rather then rely on an external debugger server.
We can also examine variable values and put them in a watch window and show the current stack : http://www.lua.org/manual/5.1/manual.html#lua_Debug
