With the divemate solution, the IrDA stack runs on the dongle, not on 
the host. The host system will see it as a regular usb device (possibly 
a standard usb-serial chip) and talk to it using some custom 
communication protocol (probably some simple pass-through mechanism). So 
the dongle effectively hides the underlying IrDA communication from the 
host system.
