Yeah, I've thought about a software avatar approach, but am sold on the substantial number of advantages and opportunities provided by a humanoid interface. A personalized interface along with a truly interactive bot (above the level of Kismet ) is the key to motivating students to do stuff they think they don't like - such as math.

Re: the DHCP thing, yes, DJ is (at last update) waiting for the vendor to provide a solution. In another thread we determined that some routers respond ti DHCP requests faster than others and mask the issue, so some people with up to 5 EZ-Bs haven't seen it, but I think thw risk would be high in a room of 25 or more of them that at least some would be problematic, and for this kind of project, you need it to "just work". You can't have a teacher spending half a class troubleshooting a few desktops.
