That is what is known as a wireless-cable or Bluetooth Cable Replacement setup. There's really nothing interesting
for you to do with regards to other Bluetooth devices since the two dongles will only connect to each other and
just pass RS232 signals from one device over to the other. Neat setup but not really providing "Bluetooth" stack
features to the operating system/user and really just uses Bluetooth behind the scenes to connect the modules
and move the data over them.
Bluetooth was designed to provide a number of "profiles" and be expandable with new profiles if someone needed
something outside the current spec. Some profiles are Serial, Headset, Dial Up Network, FTP and many more: http://en.wikipedia.org/wiki/Bluetooth#Bluetooth_profiles
It's really a nicely design wireless system and it's not just for short range use and can operate from 10m - 100m.
