customizing XDA's today screen - MDA, XDA, 1010 General

Is it possible to customize the XDA's today screen (i.e. by using XML) as you can do with the Orange's SPV ?

Download Microsoft's Theme Generator...
http://www.microsoft.com/mobile/pocketpc/downloads/powertoys.asp
There are some other goodies on that page aswell.
Good luck!

Powertoy is not what I am looking for: the idea is not only changing the background image but to organize all the datas on the screen as and where you wish (date, time, numbers of emails received, fonts, etc.) as you can do on smarphone 2002 changing the today screen's script in XML.
For examples what you can do with Smartphone 2002:

It's a bit more complicated with PPC 2002. Unlike smartphone, it is an API to change the contents of 'Today'. Each line is loaded as a type of 'snap in' dll.

Do you I could find some examples of that kind of work ?

It is really a pain in the ass

Thank's !
Is there somewhere a technical documentation about that ?
