 2 - Considering you still need a templating and formatting framework, I began wondering if the base class should actually not be TikiDB.php but something else (TikiSystem maybe?). TP classes are all inherited from TikiDB - meaning it needs to be working with a valid DB connection before you get anywhere. As much as it would prove useless, I believe that if our base class should do basic formatting, themeing, templating, etc - and DB connections should be secondary to this. This would allow the install to be better integrated into the kernel and in theory be more stable.

This should, in theory, provide a more stable and streamlined kernel to be merged back into Clyde.

 So, here's what I've got in my head...

 The reason for this - the first page of the install could be used to select a language (and maybe a theme), without necessarily having a db connection, preferences or users for that matter.
 
-If we can build the kernel to support these functions, without a database or users, it would be perfect for the installer and provide and even more stable kernel for Tikipro. If we can present smarty templates, in different languages, different themes, default preferences, no database, no users - we will have a rock solid foundation to build clyde upon.

 I have suggested we move AdoDB and Smarty to utils/, as they are 3rd party code and libraries and should be kept seperately for updating seperately.
 
 !The Future
-This is the future of Tikipro (as I see it anyway). If you have ideas for fundamental changes, this is the place to raise them, and submit if majority agrees.

 !Preflight Sequence of Initialisation
-!!What to Check
+Packages should be able to register check required for them to work for any of the items below. Registered checks for package version dependencies, etc should be utilised.
+
+!!System Requirements Check
+!!!Preflight library functions
+!!!Writable temp and storage directories
 !!!PHP.INI settings
 The code here should __ini_get__ settings and compare with recommended values. If they do not meet recommended values, either (to be decided) set dynamically or advise to change in the PHP.INI file.
 !!!PHP Libraries
 Check to see if suitable libraries and versions are available, such as GD, ImageMagick, LDAP, MySQL, PgSQL - possible even AdoDB and Smarty (I've noticed FC2 now comes with an AdoDB rpm).
+!!!Compatibility Functions
+The PHPCompat library could be used for older versions of PHP to allow functionality with checks for function existence.
+!!!AdoDB, Smarty and other required 3rd party libraries
+Rather than hardcode includes, we should use the library path to find these libraries. This will allow system wide references to a single library install.
+
+!!Install checks
+Check for essential packages such as kernel, users, themes, langs and util. Possibly include package version checking.
+Check for suitable libraries (under /util/) and versioning.
+Check for temp folder r/w access (templates_c, cache).
+
+!!Administrator User
+Is an admin set? Do we need to use admin password to continue installation.
 !!!Database Connection
 Using TikiDB, check for valid database settings/URI and connection.
+The installer and preflight will probably have to do different types of checks - at least during the first install. Perhaps the checks on revisiting the installer can be the same, i.e. if the file config_inc.php is already present.
 !!!Database Tables
 Check if core database tables exists, such as users_users (for admin account), tiki_preferences (for preferences), etc.
+
+!!Initialisation settings
+Check if important things are set, such as storage path.
+
+!!Package selection
+What packages are installed / are they working? can we check that? is it worth checking?
