As I already noticed when searching for my name on Google someone already took my LGPL licensed class and did some hacking on it in the meanwhile forgetting to retain the copyright notice.
To countermeasure that kind of behaviour I've set up 2 github projects which PHP users might find intresting.
WowPhpTools
http://github.com/christiaan/WowPhpTools
This project aims at bringing a standard to fetch data from the Armory and Wow-heroes.com using PHP. For now there are just two methods implemented, one to fetch data specific for one character and one for fetching a full guildroster (for wow-heroes just the guildroster part).
It should be fairly easy to extend it to support the other features the Armory offers.
WowPhpToolsWebService
http://github.com/christiaan/WowPhpToolsWebService
This project is what I'm running at http://christiaan.baartse.nl/WowPhpToolsWebService/wowheroes/?c=christiaanisgek&z=eu&r=outland&g=mysth for now it basically implements the JSONP format for both Wow-heroes and the Armory.
Using that last service it is fairly easy to create Javascript widgets showing a guild listing either by fetching it from the armory or by fetching it from wow-heroes.com.
If you'd like such a listing you can provide me with a design of how the list is supposed to look like and I can turn it into dynamic javascript widget for you.
Edit:
Example widgets just copy the source and change the guild realm and zone to see a listing for any other guild.
