Yes, it would be interesting to see Apple's response. Now I remember what made me ask this line of questions in the first place.

In the release notes for J901 iOS I saw the following:

"it is legally impossible to release a J IDE for iOS as an open source project due to restrictions imposed on app developers by both Apple Inc and the Open Source community".

Although there was no justification for this comment, but maybe it's just true due to enforcement.
