The signup process is extremely simple. Type in a username, enter a password and it creates an account. I'm the first one to complain about needless signups but to make your own schedule and have it printable in a decent format, signing up is pretty much the best solution.
I just setup iCal export for your selected sched.org events. My username is 'chirag' so my schedule will be http://sched.org/sxsw2008/chirag and iCal URL will be http://sched.org/sxsw2008/chirag.ical
If you use Google Calendar, you can import this directly.
This is a very specific tool with a narrow market/target-audience and not meant to replace anything general like Google Calendar or Eventful.
This is the database: http://schedule.berkeley.edu/
This is the app: http://www.ocf.berkeley.edu/~amanb/makeSched/
Your app is the perfect interface if it can hook into the Berkeley schedule database.
in fact, use the berkeley schedule for the data backend and i would switch to using this over the other hacked together schedulers available.
