Create an Appcelerator Titanium module OCR

We are looking for an OCR module to use in our iOS application developed in Appcelerator Titanium. The module will need to be writted following the Appcelerator Titanium Mobile iOS module development guide (http://wiki.appcelerator.org/display/guides/iOS+Module+Development+Guide) which needs to be written in Objective C. In its simplest form the module method needs to be able to accept an image from the Appcelerator app, analyse it and return the resulting text. If possible OCR conversion can be done in real-time and return the result only when a text is recognised in the camera. Module should support iPhone and iPad.
