• use internal DateTime class instead of PEAR (http://derickrethans.nl/files/time-ffm2006.pdf)
• use internal SQLite for tmp storage, ie Config container
• use input* functions for input filtering (http://uk2.php.net/manual/en/function.filter-input.php)
• utf-8 only
• get rid of modules in main distro (allow core framework to run with no modules)
• create subdir to version modules
• implement a plugin system to add modules, themes, ... (see RFC/Plugin)
