Wow...nothing! And then I see that someone else can ask a question and it gets answered so it definitely got read. The proper etiquette would be to respond. Even though the answer is no, which is obviously is, a response means your not ... ah never mind. I will build the addon with brute force.
Sorry for late reply, but I'm quite sure this also got answered on several other threads: we're not interested in making a wow-heroes gearscore addon and we're not in a position to give away the formula (not to mention that it gets updated often). If you wish to make an addon, good luck with it.
As with others, I am also in support of an xml export for single characters. I'm currently writing a .net application for my guild to check the gear score of others for raids in a more efficient manner. Currently I have to parse the web site for this, which increases the server bandwidth for WoW Heroes. I would love to save the throughput for other users with an individual character xml pull.
Thank you guys for all your work on the XML export in the first place, I've used the guild export for scheduling raids and it has helped a lot!
Minimally I would like the same data you are exporting now for the guild character export. It would be nice to additionally have the off spec name, talents, and gear score as well. I think these items would probably cover everything I would use it for. Thank you for your quick reply!
