Tear, just wanted to let you know that one of the things I spotted when I was visiting the production offices for HBO's Game of Thrones ... were several copies of your map, printed out and stuck on walls! They had been sent to them by George, and they loved the detail they had which they said had been very useful. They're making their own maps for the production, with a more historical style and focus, but I think yours is definitely a reference.
I have a picture of it on the wall of one of the offices. Not a great picture, but still. If you'd like it, drop me a line at firstname.lastname@example.org and I'll mail back a copy.
