Edit by Reid:
I implemented the above as a Python script that makes wrapper scripts instead of aliases. You will need to put ~/bin/mankoffmagic in your path. If you want the wrappers to be updated automatically, run it regularly from cron or somesuch.
#!/usr/bin/python
#
# This script automagically updates a set of wrapper shell scripts in
# ~/bin/mankoffmagic which call Mac apps installed in /Applications.
#
# Inspired by mankoff's shell alias posted on apple.stackexchange.com; see:
# http://apple.stackexchange.com/questions/4240/concisely-starting-mac-os-apps-from-the-command-line/4257#4257
#
# Notes/Bugs:
#
# 1. Does not follow symlinks (aliases?)
#
# 2. Assumes that application names do not contain double-quotes.
#
# 3. Not very smart about finding the actual binary (it guesses). This is
# wrong sometimes, e.g. Firefox. Probably a deeper understanding of the app
# package structure would fix this.
