Jimmy Wales:
I think that GNU FDL is perfectly fine for Ultimate Wiktionary and there is no need to change the license. The license is perfectly compatible with the .DICT format, so there should be no problems at all.
Jimbo,
could you give us an update on where we are with regard to CC-BY-SA/FDL compatibility? Might it make sense to organize an electronic meeting with Wikimedia's legal team and the CC/GNU folks to speed matters up? Sorry if I'm out of the loop on this.
