The challenge with presenting with the iPad in many locations is that the existing infrastructure is configured for laptops and this means connecting via VGA and this can result is restricting the iPad mobility; one of the reasons to be presenting from the iPad in the first place..
DIRECT CONNECTION
You can directly connect your iPad using the Apple VGA Adapter (MC552ZM), this results in your iPad being tethered to the podium. If the VGA cable is heavy you can pull the adapter from the iPad as it is a non locking connection (compared with the laptop which uses screws to lock the attachment to the laptop). Some of the very heavy VGA cables place some considerable strain on the iPad dock connector.
The Apple VGA Adapter supports video mirroring on iPad 2 or later and iPhone 4S; and video out (only) on iPad (1st generation), iPhone 4 or iPod touch (4th generation).
This can work and is worthwhile carrying the adapter in your iPad case if you are presenting from your iPad. This is not a good solution if you control the space that you plan to present in.

Making it work in our environment.
To allow for the AirPlay in our environment we have created an ‘iLab’ that can be installed into classrooms where the iPads are being used. At the moment the “iLab’ resides in one of our Science labs and is moved when required elsewhere.
* Video is converted from HDMI output from the Apple TV into a VGA signal using a Digitech HDMI – VGA/AV component converter. This gives a VGA signal that can be plugged directly into the laptop video input.
* Digital audio output from the Apple TV, we convert the signal to analogue audio using a Digitech D to A Audio converter to plug directly into a 3.5mm audio jack provided for the laptops.
A custom wireless network is provided using an Apple AirPort Extreme. This allows for access control specific to the class, and access to the internet can be supplied and removed without impacting other users.
All of the required components apart from the AirPort have been mounted onto a 1RU rack tray so that the unit is very portable and can be installed into the teaching environment when requested.
