HUD scripting: Notecard Reader

Im looking for a very specific type of scrip to use in a HUD im designing. This script should do a few things: First, it needs to read a notecard which is loaded into the contents of the object, which can be moddable by everyone.

Second, it should take a texture UUID from said notecard, and place it on a specific prim on the HUD (Which could be a logical position..Im considering putting in up and down arrows for selection purpsoses).

Finally, From the Notecard, the script should pick up the name of scripts (which will be added later...think "Modules" which will provide the HUD with button functions which will be integrated.
