I've used this system on cp.org and another private forum i run, and i remember being hacked threw a mysql injection exploit in the store. So i would definitly make sure that the code is safe, which im sure WW would do in the first place.
The way the original system works is you gain points threw post counts, threads counts, and referals. Also allows Staff to donate any amount of money/points/gold (whatever the forum wants to call it).
I would suggest hacking this soley around activity, and longevity as no one can tamper with that system that I know of. And not allowing any Sup Mods, and Mods to donate any amount of money as that will cause for abuse. Donating your own money should be fine.
The referals is also something that i wouldn't have active seeing as anyone can run threw proxys to add a new user name to gain a referal point. (if there is an IP checker) I think it would promate some more activity and also get alot of the D2 members out of the D2 forum and start posting with the rest of the community. Good thinking KA i finaly agree with you on something

. I say it would be a great Add-on to zelaron. Finaly put some spice back in here.
