Nope but if your sleeping with anyone on the Google Tech team please do tell what you find out
For the record I know that Dmoz has made a really new dump for Google and others to use, but if they have picked it up and are using it, that I don't know. That any way is what is being claimed is the hold up for the dmoz.org pages from being updated, the dump being more important because 10 times more people use directory.google.com than dmoz.org... not a big surprise that.
