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!
