Baen makes a lot of their SF books available as ebooks for free, and they occasionally do anthology/theme CDs. Thanks, Baen! (I'm not buying their webscription stuff, because the free material is good enough for my palm pilot and otherwise I mostly prefer dead-tree books, so I'm still a supporting customer.)
This guy here offers most Baen CDs via Bittorrent, and the stuff works great :-)
