please try to distinguish 'cross platform compilers' from using alternate languages to write for Cocoa APIs. it doesn't matter if you're using C# or Ruby, your program is still structured around all the native APIs necessary to function. Unless somebody reverse engineers a similar platform with identical APIs (and thus, likely built on Obj-C as well) you aren't getting around targetting CocoaTouch specifically. And there isn't anything stopping anybody from releasing cross-platform-compiler 'meta platforms' which DO use Obj-C and thus qualify under Apple's new rules.
