Thanks for the update!  

I was interested to follow the story about that power-on-password request.  You know that teacher was with the pre-K until this year?  We had decided to just offer her INsight to control the computers (and did install that), but when we described power-on-password as an alternative she asked for that too.  Since that didn't work out so well, your solution of disabling the school's shared student login seems like a good thing to try next.  

Cheers,

P.S.  When I stopped by Ray last week I meant but forgot to take a look and scratch the itch of curiosity about whether the lab desktops that are plugged into Ethernet have their wireless disabled (in HW or SW) as I half-remembered.  If you have a chance, could you comment with perspective from Ray's setup (along with your own view) on the thread Tom and I have been commenting in, under posting "Tech Question"?  Thanks again!
