All ...
We are waiting to hear back from Barracuda about our requirements.
We have also contacted http://hotelwifi.com. They sell a "Fusion 1000" gateway device designed specifically for hotels. Their website does not say much -- just a datasheet: http://hotelwifi.com/fusion/index.html. Much of what we want is in this single box. We are waiting to hear back from them. The sales rep says he is confident this will work, but every sales rep at every vendor we have spoken to has been confident ... until we get to the 1b requirement!
