You may be interested in a project we are currently working on for wireless testing. We are building applications so that students can answer questions in the classroom as the teacher asks them, and the grade can not only be recorded immediately, but the teacher can get a better grasp on how well their students are learning the material. We also have several other uses we've considered. The link is

Dear Tarwn,
Thanks alot for your concern, it seems that you are working in a big projects..

I have done most of the hardware part ... Wired every thing is ok... i only wait to get the Transmitters and receivers modules...(Unfortunatly most of the equipments will be funded by ourself )...

my big problem now is Office Programming ... i'm new to VB and it needs an expert that i couldn't find here till now..
thanks again..and i hope that you succeed in your project..good luck..
