I know theres still a hack out there for that but please do not forget also the new database support for this.
means there should be ONE database for the whole comming installation.
if user is alowed to see or not is another part. but it make no sense to have additional to every user datadir and own user mysql database.
i dont know if it isnt already made (cause ife some problems with the cvs version
if needed we can do it with prefixes so we can use username or domainname as db prefix
