I don't speak italian, so please forgive me for posting this in english.
I haven't looked at JoomlaFAP yet, but are you aware of the Accessible Joomla! project at http://forge.joomla.org/sf/projects/accessible_joomla
? We have been working on this for about half a year.
I was wondering what the changes are from the joomla core?
I was a little surprised to see a new accessibility project. I would have been glad to work together on some areas. I still am of course
Maybe we can share some code now and then.
FYI, there is also a 508 hack from run-digital.com to make joomla (more) 508 compliant.
PS. Maybe you should change FAP to FAIP (For All Italian People)
