Is anyone using Wi-Fi In Motion?

I either use my unlimited data 4G phone or a dd-wrt router functioning as a virtual access point for poor cell service areas where only campground Wi-Fi is available. The VAP allows multiple devices to log onto services like TengointerNot. To me, the phone is the ideal solution as you can take your hotspot anywhere. Dd-wrt converted routers can be picked up on eBay for around $30. I think there is even a kit with an exterior antenna called something like JaffaTech. I added a 3' antenna to mine but saw little improvement. Bottom line is there is signal or there ain't. If I consistently was camped in a signal challenged area, I would consider a pricey solution but not one of the "Wi-Fi in Motion" gimmicks. The goal is get something up into the air to grab over-the-horizon signal. I can also VAP my 4G hotspot through the router and achieve a much wider coverage radius.

It seems Cradlepoint's and Wilson's are reasonably priced boosters too. Alfa makes a $50 AP/repeater also.
