There is also the path the Multi Theft Auto mod[1] took: they host a compiler[2] on a server that signs code, trying to load() bytecode that was not compiled there (ie.: string.dump-ed or emitted by luac) gives you a runtime error.
Not sure if that's a good idea though, I always found it weird that servers are so protective of their mods and want to compile and obfuscate everything.

For the record, it is perfectly safe to run bytecode from trusted sources,

Lua compiler is safe; handcrafted malicious bytecode is not.
