Ad-Hoc networking with Bluetooth

Hi,

Using 802.11b adaptors, I set up an Ad-Hoc network between my desktop and
laptop and can map drives, share printers and internet etc no problem (using
win-XP)

My brother has Bluetooth adaptors on his desktop and laptop (win2000) and I
just can't seem to map drives or share printers. Within the Bluetooth
software you can fileshare, but that just opens a copy of the file, not
actually read/writing directly to the remote device.

Is this a Bluetooth, Win2000 or Stupid User "thing".

Can you use Bluetooth to set up a similar Ad-Hoc network as with 802.11b
adaptors etc?

Many thanks.

Darren.
