Tyler,

This embedded version of Lua does have some limitations, including the ability to call out to the OS shell. From Paul's paper:
Currently, PROC LUA does not support all the modules that Lua provides. For example, PROC LUA does not currently
support the os module, which offers direct support to the operating system. Lua’s language features for multithreading
have also been disabled.
The Lua community has created a large set of Lua modules that are available online. However, you might find that
some third-party Lua modules do not work in PROC LUA. In particular, if they were written in C or involve custom-built
C libraries, PROC LUA cannot run them. Lua code that is written for a Lua version other than 5.2 might need some
modifications to work in PROC LUA.
