I have occasionally wanted to trigger location-specific behavior on my kid's devices, like turning the wifi off when in their bedroom. This feels broadly in the category to me.

Couldn't you do this with your router/firewall? Of course, this would mean managing devices by MAC instead of DHCP, but one of the wifi routers (maybe a Tomato upgrade) allowed designating blocks of time to allow/deny WAN access
