Navigating links shouldn't be an issue assuming that the app hosting the web view is allowed to connect to the network.
But how about plugins loaded by the web view? I assume that's what's happening in my case. The web view is loading the Flash plugin, which in turn tries to access the file system.
That's not allowed, because the plugin inherits the entitlements of the parent app. The Flash plugin really can't believe that access to it's Library folder doesn't work so it tries and tries and tries sending the main thread into an endless loop blocking the complete app.
That's actually what I meant by navigating links. Each page would load fresh content that might have plugins that require services not authorized in the main app.
For example, any typical RSS reader, alternative email clients, specialized browsers, or any dev tool that shows page previews using a webview. These all have to max out the entitlements so they don't break down the line.
It seems like it would be much more useful to make entitlements be a dynamic system instead, so apps can request extra privileges at runtime and asking the user to confirm instead of statically baking it into the app envelope. Same goes for the iPhone.
