I just played around with a wiimote on my pc and
explored the data transfer and networking
possibilities of bluetooth.
Holding in mind, that you can get a usb-bluetooth dongle
for 1,50 Euro I thought that is one thing the PS2 should
OK, BT is not the fastest thing (3MBit/s) but has the advantage
to be wireless.
I have no doubt how many calculation power is needet to do a driver
or how useful it would be, but it would be nice to have something
to play with.
And may be interesting for people without network adaptor.
