There are two issues ... Global Data and the more dynamic data (PC - Stack
etc..) If you can do with the global data one of the best way (I'm doing
this also) is having a export/import function to/from XML (XML is a good
format for storing the tables).... I think lhf posted a Lua source for a XML
module some time ago - look in the archive - Mine is programmed in c and
works with a special database.. If you want to store the exact lua_State you
are in for a major task .. Almost all information in Lua is alloc'ed
dynamicly so would would have to travel all structs and build a map... Huge
task :-)
