While this is all true, the GFDL *is* fairly far along the process of being rewritten, and the FSF has seemed willing to consult with Wikipedia about its needs during the process (I believe Jimbo has been queried about it).

So I'd personally lean towards waiting to see if the next GFDL is something we can live with, before trying to relicense the whole encyclopedia---a huge and messy undertaking.
Exactly, I think that the best thing to do is to try to negotiate with the FSF. A change in a new version of GFDL would be ideal, as it would affect instantly all the current content of Wikipedia and we'd avoid the licensing hell by having just one license.
