Sounds like you have a great plan. One thing that may help with the internet is that Exede is launching a satellite (Viasat 2) soon which should enable them to dramatically increase their monthly data cap. We believe our 30 G/ month plan could go up to 75 or 100 /month. These companies know their market share depends on overcoming the low data caps, with the current Viasat satellite speed is not horrible, but the data cap is a killer if you stream any video or work with graphics, etc. There is also a Viasat 3 in the pipeline. However, there is no cure for the latency issues, even with fast data rates there is a long delay.
Straw bale works really well in our dry climate. I'd be nervous about it in PA. One risk is getting bales wet during construction before stucco. Our schedule was complicated, I was burning vacation to stack bales so I didn't have a lot of flexibility, and the stucco crew was late finishing their previous job, and then we got several days of heavy rain while waiting. I had tarps up to minimize damage, and then we had about two week of dry sun, but I did end up tearing out several sections of wall because I feared the bales were damp internally. I don't know how you'd ever get them dry enough in a humid climate, although I recognize there have been a number of successful projects in the northeast.
Another interesting alternative which can be thermally efficient if done right is cord wood. There are a few structures around here but I didn't see them build so I don't know about their R values. One of them used a lot of blue bottles for light in the wall, it looks pretty cool when the sun hits it. It looks like you can have a good combination of thermal mass and R value if you do it right.
