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
get
# different content according to their language, preferences and
permissions.
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 :-)
