IPCop is actually pretty good for this as it uses one of it's interfaces for wireless access based on granting each node specific access by MAC, but it can be any network node, it doesn't have to be a wireless device.Hm, don't know much about IPCop but I would have some doubts about it authenticating wired users on a local network.
That's good to hear. Again, I just need to find the simplest implementation possible for starters.You are on the right track with wireless.
