The C++ code written for SahanaPHP (during GSoC 2007) can almost-certainly be tweaked to work with SahanaPy:

This version uses ​OpenCV & ​FANN

A Firefox add-on to enable a nice workflow for users is being developed for SahanaPHP as part of GSoC 2009:

• ​http://sahana.cvs.sourceforge.net/viewvc/sahana/sahana-phase2/bin/ocr/?pathrev=gsoc_2009

This will access the Scanner (e.g. using TWAIN or SANE) and read the Image. The acquired image will be passed to the OCR library & the result will be posted into the web form.
Again, this should be easy to tweak to get working with Py.

Possibility of using pytesser ( ​http://code.google.com/p/pytesser/ ) with cross platform tesseract-ocr ( ​http://code.google.com/p/tesseract-ocr/ )

Plone uses Tesseract: ​http://plone.org/documentation/tutorial/ocr-in-plone-using-tesseract-ocr
