I want to provide limited internet access for a crowd of people (~50) who will be attending a 1-hour talk of mine, at a conference where wireless is not provided. But I want to give them access to a particular server, so they can actually use it during a "hands-on" part of the talk. The site serves html and does ajax interaction, so it would be important to have low latency, but I don't anticipate needing much bandwidth.
Is it reasonable to try using the following configuration?
(usb internet connection -- my computer -- wireless router -- the crowd)
In particular, does this give me the capability to restrict the crowd's access to just one server? Do I need any special software on my computer other than the usb internet connection interface? For this level of traffic, is a consumer router and laptop probably ok?
