Bluetooth Application for Mac OSX

We require a Bluetooth App for Mac OS 10.4 and 10.5. It must do the following: 1: Search for all nearby Bluetooth devices. 2: Send selected file(s) to device, from a selected folder 3: Repeat process continuously Other features it will include: Auto Launch, Must have GUI (nice looking), must keep record of sent files, must not resend same file to same device, keep a list of devices that decline file request (ie blacklist). We have an App that does almost what we need, we would like it recreated or modified to work on Mac OS 10.5 and have a few small changes. This App can be sent to you as a reference if required. Many thanks for you time, Simon
