Does the unity web player work on the iphone And iIpad?
no… no plugins are allowed on the iPhone or iPad
Would it be possible to create some kind of Unity app for iOS that streams games to iOS devices?
For example:
Developer with a decent library (or partnered with other developers) creates said app and releases it for free.
Developer charges some kind of subscription fee that allows user access to aforementioned library.
User chooses their game from some form of mini-storefront and it streams to their device.
I’ve never used an iOS device or the marketplace, but my thoughts are:
This has been done already, Apple doesn’t allow this sort of ‘mini-storefront’, or that there is no way to stream in that way.
Sorry if this seems a bit off-topic, I just thought it fit quite well with the topic, as it’s more or less what Bikebreck is asking about.
Yes it would, but only if you solve one of the top 3 ultimate problems: how to have any possible code mutation in a single application 
Cause all games need to use the same shared code, they can only exchange assets, but they can not transport any code as addition of code is:
- not possible
- even if it were possible, its not allowed to add code through downloads
