According to Wikipedia, alt modes include DisplayPort, MHL, PCI Express, and Ethernet. I really hope USB doesn't make the terrible mistake of exposing an insecure protocol like PCIe over a "public" port. With FireWire, I could just destroy the port physically since I didn't use it. But if USB gets the Apple treatment of giving DMA access to anyone that can get a peripheral connected to your machine -- well, that'd suck.
