Deborah J. Ross wrote about the "Lands of Islam" panel at Islamic fantasy panel at World Fantasy Convention. She has an earlier post about prepping for it: Groupmind help on Islamic Fantasy.
Perhaps the most important point: Islamic Fantasy, Arabian Fantasy, and Middle Eastern Fantasy are not the same.
I liked the panel a lot. It inspired a question I'd like to explore someday: What is the writer's obligation to accuracy when dealing with folk tales? (My quick answer: know enough to avoid stereotypes, if only because stereotypes will bore or offend your readers.)
Our Liavek stories were mentioned favorably, which was sweet.
