Array of pagemediaselect fields in Admin Form?

Would there be any way to combine the file selection of pagemediaselect forms with the addition and subtraction capability of the array form?

I'm building what I hope will be an awesome slider plugin, and this is the final piece, essentially.

Okay, so I figured out the solution to both this question and my question above. They turned out to be related! By using the "list" type, I was able to set up exactly what I wanted! Awesome.

Nice!
