Well, as long as this is in beta I can't submit iPad apps compiled with the 4.2 SDK but I have to use the 3.2 SDK.

But I tested version 1.1 with 4.2 beta 3 and it's working like a charm. Of course I'll be sure to submit an update as soon as Apple allows this.
That would be a pretty cool feature!
I think I found the problem. It should be fixed in the next update.
This is now possible in 1.1.

You can re-enable the GettingStarted file in settings.
The features I want to have in 1.1 are mostly implemented. I just need to add some finishing touches and thoroughly test it. I hope to submit it to the App Store this week.
Local Web Preview is implemented. Will be available in the next version.

I've posted a demo on YouTube: http://www.youtube.com/watch?v=tAq6W5wnNAk&hd=1
Unfortunately, it's not possible to load something like shared modules or dlls. Everything would have to be included in the executable...
Yes, that's true. Licensing is a big problem here. I can't include GPLed code.

I use Subversion for my own projects, so that's also the version control system I know best.
