network message

[zombiesnooo!!]

I have an open network in my home because I don't mind casually sharing bandwidth with others who could use it. I've been saved (in a big way) multiple times by someone else's open network and take a pay-it-forward stance.

My question is this: I'd like to send a message to people who log on. Is there anyway that I can (easily) do this? I'm thinking something along the lines of the homepages that many city-sponsored wifi networks have.

I imagine that you could set up a redirect when people initially connect to the network and fire up a browser, but only have it happen when computers with new addresses connect (otherwise you'll see the message when you connect as well). AFAIK, this would have to be done using a dedicated box, because most - if not all - routers don't suppose this kind of setup. It is probably a complicated setup with a Linux box that monitors clients and acts as a DHCP (router) server. Certainly possible, but probably requires a lot of tinkering.
