Well, I did end up going with something commercial, as I will be in a field and need to get a reliable link between the two machines. I don't think I'm going to have time to work on this aspect for more than a few minutes as we need to collect data in a short time period. Work IT came up with network express cards and they tell me they can provide them inside a week. I'm told that the field I will be in has cellular access so I'm crossing my fingers it works. If it doesn't I will just need more generators put in and a trip to staples for several WAPs. I appreciate the help. My deciding factor was really the time required to get in products and test them. I had to write a non trivial amount of code as it was to control the hardware that we will bringing with us, so I had less time to hack on this. Just in case I do need to fall back on plan B, what can I expect for range in a field (good line of sight) from a typical WAP? The weather conditions will probably be extremely warm and humid, I guessing the heat index will be at over 100F.
