We no longer support the Single Edition-style of apps. Your end user will need to have a network connection available to initially obtain the content, although once they've viewed it we will cache it on the device.
1) The current Beta version I have made does not cache content as you describe. Is this because it is Beta only?
2) Also, the Fast Company app which I am told uses this new version of DPS, does not cache content either?
So, for what it is worth, Adobe seem to have turned the DPS concept into something which which will be less useful for customers who wish to deliver a fully rich media experience via DPS without a connection once the app is downloaded. It has turned DPS into a web browser only. Very disappointing, I don't expect to be able to sell this idea to any of my customers.
It will also be interesting to see how many of the current publishers continue to use DPS going forward and how they adapt their offering.
