I'm more interested in option 2. I have plenty of movies on my laptop, but it would be fun to be able to stream anywhere in the campsite. I would never pay data rates to stream movies. What a waste of money! Anyway, to me option 2 seems better for most campers who want to keep the kids away from nature and plugged in to the machine.
Use a WD with a 1tb usb. First camper with 2 tv's so I'll have to think of a new mod. Most likely a d-link wireless router with the usb nas port. Yes, when I talk to non camping people about camping their thoughts are we are roughing it in tents in the mud...not that we all have the creature/techie comforts like home.
