Recently I update license of NObjective to LGPL so commercial apps can now
link with it. I can't change license to MIT X11 coz I want to be main
developer of that library. I can specify separate license appropriate for
using it on iPhone.

NObjective's class exporting system can be easily adopted to work without
But my code dynamically generates a lot of small chunks of x86/ppc machine
code for each exported method that used for cross-runtime exception
rethrowing ( like Mobjc project does via libffi. But my approach more
efficient ) so it can be problem. Currently mono for iPhone not available so
there is no way to test NObjective on it.

Also now my library internally have Objective-C lexer/parser ( NObjectiveAST
) written in C# and with its support I can regenerate all objective-c
proxies in few seconds.
