Disable uninstall from Add/Remove Programs, enable maintenance mode, which will show a GUI during uninstall. Then allow user to uninstall from maintenance, typically through a radio button selection that sets REMOVE=ALL. The you can prompt the user for what you need (e.g. a SQL password to drop a database, etc.)
Set up the silent uninstall to proceed from the command line silently if you want this feature by passing in the proper parameters from the command line (e.g. "SAPWD=<BASE64 Encrypted Value> SERVER=<MACHINEZ_SOMEWHERE>"). But you won't be able to run this from ARP although.
