Being that I am a complete noob with Ruby/Rails, this may be way off
base. This past Saturday we were talking about our app having the
ability to be placed on a flash drive and ran anywhere. I stumbled
upon Sinatra, looks like it may be an option for a small app that just
produces a one day workshop. I also watched the presentation from
RubyConf 2008, it looks great for a small portable app. Have a look
and see what you think.
