Oh! So you really would like me to bring my laptop. Okay, I can do that. I thought you were joking!
My laptop is wireless capable also... I know you said expense.... just want to tell you it's available. But, since you need it, I will bring it.
It isn't the wireless computer that is the problem. Ramius has a wireless LAN at the beach house that will reach down to the boathouse. (You should check with him and see if your internet card would work there before bothering to bring it) It's the wireless ~camera~ that is expensive. Like $250-$400 for ones that have any features at all, like a good picture and the ability to focus it and adjust for light. A good wired one (USB) is in the $60-100 range.
