How many is that? Have network connections really become reliable enough across the entire country (where a major-ish chain fast food restaurant would be located)? I honestly have no idea, since we (on HN) tend to be more focused on broadband, whereas this is more likely to be adequately served by what are low bandwidths by today's standards (albeit not as assymetric as the consumer Internet, which can be another confounding factor).
