TUAW reports it's possible to some more USB ports to the MacBook Air with some modding:
Apparently, the Air has a few extra live USB port connections built into that thar skinny little computer. How do we know this? Because the guy downloaded developer documentation for the ICH-8 chip, which offers 5 low-speed and 2 high-speed USB controllers.

He popped open his Air and measured the voltage at each pin. He then used a hacked memory key with a modded USB extension cable (with an extra resistor just to be safe). After connecting the memory key to one of the pins, his MacBook Air system log reported a USB error. A few more tests and adjustments later, he actually got his laptop to recognize the drive. In total, he found three working USB connections plus an unused SATA controller.
