Wifi is rulled out. I googled more, and found solutions in similar lines as nylerididog. It is ruled out because, ad-hoc networks can not use WPA security. Though WEP security can be used, but I do not want WEP security.

I will try bluetooth. I found something at http://www.palminfocenter.com/news/8...th-windows-xp/ I havent tried this, but will try in couple of days and post the full process here.
