Working on Portals, related questions

Well that one is a bit more involved, since it is using a multi-callback - one callback for coords, one for heightmap, another for biome map, blocktypes, blockmeta, ... Have a look at cChunkDataCallback in ChunkDef.h. Now I don't know how to make that Lua-accessible easily - should the function take a gazillion arguments, one for each callback function? Or a Lua object with functions assigned to it for each callback? Also, my Lua hacking skills are not up to this megatask.
