COLM MURPHY gets a page in Computerscope to rant against open wifi access. I don't see the problem with running a low power wifi node from your router that allows guests a free internet connection. I haven't read of any worm that wirelessly attacks a router and compromises file integrity. I never heard members of the Irish Honeypot project criticise Eircom when all its wifi nodes were free and open to all comers. So I am beginning to believe that pronouncements against free wifi access in public spaces are disinformation. My node in Cashel is wide open to anyone transiting the Golden Road. Enjoy. But don't expect to see the wireless connectivity that serves up data between rooms in my house.
