The easiest way will be to abuse a SecurityPolicy class. It is notified 
about each read or write action, and return True or False, but it can 
also do anything you like :-)

To get the page html, I think you want to use something like this your 
SecurityPolicy, when the user is allowed to edit:

	# Invalidate the page cache
	import caching
	caching.CacheEntry(request, page, page.getFormatterName()).remove()

	# Render the page
	# You may need to hack the current user while rendering, because users 
	# different content according to their language, preferences and 
	html = request.redirectedOutput(page.send_page, request, count_hit=0)

	# write the html here...
	return True

Check util/antispam and search MoinMoin wiki for SecurityPolicy

Document your hack in the wiki when you finish :-)
