Check out Electronic Art's description of the upcoming SPORE Origins game for iPods and iPhones:
Eat or be eaten when you play SPORE Origins on your iPod. Guide your spore through its evolution and shape its destiny. Devour smaller creatures, explore primordial worlds filled with bizarre organisms, and avoid larger, lethal life forms. Grow from single-cell to complex predator as you rise through the levels. Customize your spore, and watch it move to the tunes in your iPod. Battle friends by importing their spores into your iPod from the Sporepedia website.
Tell me that last sentence doesn't sound an awful lot like "importing a virus" onto your iPod. I sure hope they secure the "spores" enough to prevent someone from piggybacking a virus on one.
