So, I have a military rugged tablet PC running Windows XP Professional. I installed TigerVNC on it, and am able to connect/view/control from my Xubuntu laptop here at the house through our router (192.168...).
I now want to get a mobile wireless plan and USB antenna and connect to the tablet with VNC over the Internet, so my dad in Florida can write me messages on it with the stylus using Microsoft Paint. I will read and respond to him from up here in Indiana.
I want the connection to be more or less constant, maybe ending a session at bedtime and resuming in the morning. Would this use bandwidth quickly? Verizon has 2, 5, and 10 GB plans for $30, $50, and $80 per month; I'd like to go the cheapest route, obviously. I doubt dad will be surfing.
