For starters, note that before I did this I verified I can delete a bucket and another account can create a bucket with the same name. So, transferring the name is fast, easy, and painless. That said, since it's a first-come, first-served sort of deal, I went ahead and grabbed these names:
"fedora" was already taken, 'natch. I didn't know what you all might have wanted, so I more or less just grabbed lots of random names. If you want me to snag another for the moment, let me know.
