Basically, a list of nodes such as glyphs, glue, etc. (LuaTeX has a
small library to represent TeX nodes.) It should output the same type
You can see a simple example of using pre_linebreak_filter on
All it does is display information on the terminal, it doesn't modify
the data TeX processes in any way, but I think provides a good example.

Yes, although I've never done that myself.

Polyglossia can now be used with LuaLaTeX. If you tell me what macro
you need for Thai I can add it to the gloss file.
