Bluetooth sharing with PC

Are you using broadband. If so, do yourself a huge favor and forget internet sharing through bluetooth. bluetooth operates at less than 1 mbps. if you're using broadband, you'll be totally bottlenecking your connection. it'll be easier and faster to just get a simple router and connect through ethernet if wireless if you really want that (though your machines musn't be very far apart since bluetooth is very limited in range). File sharing should be a LOT faster if you used ethernet or 802.11b or g.
