Well you could get an alfa and an OTG and connect it to an android phone. From there you would use the kismet packet capture app on the device, and if you could even get some static aircrack binaries from the bcmon project. The problem with this is it would be entirely passive so you couldn't do any wep replay attacks, or use reaver. That being said using an alfa on android could work, but I don't believe it's been done yet....probably would be possible especially with a backtrack chroot.
