Dick O'Brien at 
Back Seat Drivers has a better feel for the Wi-Fi problems than I have. 
He talks about how cheap it is to set up, which is a negative if you're thinking of investing in such developments. The 
Independent mentioned this too, but because they were referencing 
Forrester, one of those tech forecasting companies, and talking about 2008, I figured that the 
Independent was just looking for the negatives. However, assuming Dick has no brief for Eircom, maybe the long-term is not as bright for Wi-Fi as I'd like.
