Distributing a Python App

[Allan Hughes]

I'm a python noob and have a question.

I would like to write a little app and then share it with others.

It is going to need to store potentially large amounts of data and then 
generate reports based on that data.

I could just write to a DB, but that wouldn't be very portable.

I would like a solution that will work 'out of the box' for any old shmo 
who wants to use it without worrying about whether they have the right 
DB.  How can I build this in?  Suggestion?  What have you done in the past?

Thanks!
