So it's very similar to Patricia's idea, but for alchoholic drinks.

A user (no profile or password needed) can text in the name of any drink. My application will translate it into the syntax needed to look it up on www.drinknation.com, parse out the recipe and text it back.

Is there a simple way to spider the drinknation site to fill up a database? If so, then I could make the application more powerful by adding the ability to recommend drinks based on the ingredients on hand.

Maybe I could fill up a database as users look up drinks. That way if drinknation changes their format, I can still have some functionality.
