+Fedora 17 Beta uses GPT. and sucessfully boots Live USB's in recent 
+tests I have done.
+
+1-)Full install of a  live .iso to a 8 GB USB; use fedora disk utility 
+to format: Custom install: GPT(boot) 2;  /boot 500; / balance of the USB 
+no swap.
+
+2-) dd write (to 2 GB USB) also works for the live .iso's
+    dd if=Fedora-17-Beta-x86_64-Live-Desktop.iso of=/dev/sdb bs=2M
+
+3-)EFI USB's that boot on a MacBookPro i7
+    ./tools_livecd-iso-to-disk.sh --format --efi --overlay-size-mb 300 
+--home-size-mb 175 --delete-home --unencrypted-home 
+Fedora-17-Beta-x86_64-Live-Desktop.iso /dev/sdb1
