It's definitely a feature we'd like to add. Right now, the software we use does not support VGA because we built the apps for both Android and iOS at the same time. We knew we would encounter this limitation, but to release the apps on the Android market we decided to go without that feature.
As another option, the apps work great on the new iPad 2 with the HDMI adapter using the mirroring feature. Our hope is that Apple will soon update its iOS to enable use of the HDMI adapter for the iPhone/iPod Touch.
