I don't think streaming video is currently desired - just basic email, access to on-line banking, and business-related web sites. This will likely expand greatly as the colonies become more familiar with the new options that the Internet will provide. I assume the base computer's connection to the Internet should be faster than any other colony's connection - how much improvement might extra bandwith give? I assume bandwith is more a bottleneck than the VPN hardware? > Basically you are creating a pseudo ISP that the clients connect to > through VPN. > Costs shouldn't be too bad.
