droll thank you very much for your help in testing. I would have tested it with myself but I haven't been switching on my N900 for quite sometime, but I will help you as much as I can anyway.

Probably this script could be useful to someone, but bluetooth tethering is so common nowaday and almost all smartdevices offer this functionality. Still it could help people understand local area network and tethering by reading our posts, I hope.
