For your interest I came across a great app for your ipad if you want to demonstrate tours offline. It's called OfflinePages and I've worked them a little to fix a few bugs we had originally, you'll see in the notes for version 1.6 'improved support for vr panoramas'. Please note though that I get no commision for refering you, I just wanted to share a great product.

The programme couldn't be easier to use, you copy and paste in your tour link while you have wi-fi access, click to download it offline and then come back to it when your offline. It keeps all your popups etc and I use it as portfolio all the time now.
It's far easier than copying all your files to Good Reader and I found that screwed up the gyro function anyway.
Give it a go and let me know what you think. Well worth £6.99!
