Jeff,
Here's another piece of code in addition to Steve's that I use all the
time as a wrapper to iterate through all shapes on all slides. Note,
I've commented out the section that you can change exactly what you
do, but the top and bottom parts are the iteration code.

Shouldn't be hard to do what you want especially if you had the list
of hyperlinks in an Excel worksheet which you could read as variable
values.
