Patching Modules (A solution.) (http://nwn.bioware.com/forums/viewpost.html?topic=574566&post=5146215&forum=47&highlight=)
Yes, it's the way resources work in NWN from what I understand. The system reads in order of module -> override -> bottom most HAK -> topmost HAK. So whatever is in the topmost HAK has the highest priority and overrides everything else.

Of course, HAKs, ERFs and MODs are just resource files to NWN (in fact, you can open up an ERF or MOD in the HAK editor). So anything can be into the HAK: models, textures, scripts, conversations, areas...

More (http://nwn.bioware.com/forums/viewpost.html?topic=574566&post=5147008&forum=47&highlight=) : PWs can also make use of this by having a top most server_update.hak and using some free tools like rsync or wget, and the erf.exe tool, let people update the hak prior to joining the server - only download the changed files, package it up automatically then run "nwmain.exe +connect (ip)".

Obviously you'd have to move the updated stuff from the update hak to the main ones on, say, a monthly basis and refresh them - and if they already have the rsync/wget tools, it can download them for you automatically.
