Well, that would work for ensuring a good connection after we have one. I want to avoid broadcasting an insecure network from each of the kiosks. Remember that the need is for us to be able to connect to the LAN on location without plugging in (we can't guarantee that the locations have wifi or 3g access or a place for us to plug in a router - unless we install it ourselves with the kiosks.) Also, a hidden network is not a viable solution for multiple reasons, mainly because osx also does not have that capability (ad hoc).
A more detailed explanation is that we don't own anything on location except the hardware that is in the kiosks. We need to be able to go as technicians to work on our computers, without having to plug an extra router into their on-site network or take the kiosks apart to get to the computers. We do most of our work remotely through logmein hamachi and SSH - but we need an on-site solution that doesn't require physical tinkering.
Thanks and hopefully that clarifies my issue.
