BTW, currently looking into the cleanest way to do multiple pages.
The basic way to do do this would be simply to rename some variables, and install the hack more than once (changing the variable names with each install). It'd be functional, but it could certainly be better and more intuitive.
To do it right would require some interesting code

ATM the only reasons I can think of to have multiple pages would be to have multiple dropdowns in the related hack, so I'm thinking of how to efficiently do multiple dropdowns / profile areas. May just enhance the page with a dropdown in it. Each option in the dropdown would show/hide the fields associated w/ that option.
Example: dropdown has 3 options: Car / Boat / Plane. Selecting Car would let you enter in fields that relate to cars, e.g. rims, spoiler, etc. Selecting plane would let you select jet engine field, turbine engine, etc.
Having a proper admin backend page for the overall hack would make it much easier to adminstrate and update though, so I'll try to work on that first.
