I am more concerned about blackout zones than time delays, since one of the "volunteer receivers" could go down at any time without warning, leaving certain regions with no coverage.
What kind of AIS receiver did you get, a stand alone or one associated with a fixed VHF like the Standard Horizon VHF.. How do you incorpoate that into your netbook? Will it blue tooth or do you have to run a direct cable.

Minnie, I have found and use a real time AIS for the I Pad/ Droids. Its not free, but I got it for free as I was one of the first 10 to install it and test it out last year. Its called Boat Beacon. I have tracked it against my Raymarine integrated AIS transciever though the chartplotter and it is dead on accurate in real time.

The new Raymarine have wifi and bluetooth capability, and an I pad app so you can use your I pad as a second monitor or remote and see everything on the CP screen. You can also upload from one to the other via USB port or wifi.
