I hope I'm assuming correctly that with 10.2 you actually meant 10.6.2.
Remote Buddy only manages the connection under OS 10.4 (Tiger). Under OS 10.5 (Leopard) and OS 10.6 (Snow Leopard), the Bluetooth connection is entirely managed by OS X' Bluetooth stack and drivers.
Whether or not using an Apple Bluetooth keyboard or mouse has any impact, I'm not able to tell. The OS X Bluetooth stack is entirely closed source.
The Apple Remote doesn't use Bluetooth. It uses IR and a dedicated IR Receiver.
Best regards,
