I use a simple AWK script which parses the available networks as returned by ifconfig wpi0 scan and selects the first known one it finds. It then creates an /etc/hostname.wpi0 for that network and runs /etc/netstart wpi0. I attached it for reference, though I think it's extremely easy to rebuild from scratch.
