The idea for online retiling has a few big problems:
While the benifits would be great, the risks would be far too great. If you can create NPC's to re-tile levels online, and save the level to the level file, then you open the posibility of anyone createing/using an npc that could retile every level with blackness and save the level files... hope you backed up your levels recently... because they are GONE.
NPC Server has made Graal more secure, but I don't think it's THAT secure yet. Maybe I'm just parinoid, but I see the potential of people seriously abusing this...
