IOS has a kiosk mode that should work perfect for this - we already use this for ipad displayed at job fairs.
Have you ever wished there was an easy way to use your GroupWise system to wirelessly display an up to date daily schedule of your boardroom, or meeting room? With GroupWise calendar publishing and a wirelessly connected tablet it's actually fairly easy to do.
I have been using this setup successfully for over 2 years using a handful of BlackBerry Playbooks and it works quite well.
Some helpful tips which I'll keep adding as discovered:
Note: Currently it will always display your notes and tasks on the right, as well as the mini calendar on the left as the gwcal webhost does not currently provide a way to disable displaying these as default, but the GroupWise developers have already added it to a forthcoming release with plans to also provide a Tablet Conference room template with this all disabled. Also planned is some cool colour coding, and auto center on current time for those who run 24 hours.
