[wp-hackers] styles, scripts & a meta box = problem

[24/7]

Hi list,

in the continous efforts to make most of my theme code generic and avoid 
coding the same stuff over and over again, I started writing my own little 
set of classes to build form fields (standard html, colorpicker, datepicker 
& media upload) for admin pages & meta boxes. At first it seemed pretty 
straight forward as WordPress even includes all of the necessary styles & 
scripts (just had to include a datepicker). 

But then i ran into the following problem (please read over here in detail 
[1]): I can't load any styles & scripts using the "BackPress script/styles 
procedural API" - wp_enqueue/register_script/style();

Meta Boxes are a great concept and have them working out of the box with 
just a call to a function is extremly kool - and same goes for adding styles 
and scripts. But what are meta boxes for? They are here for adding 
additional input fields. And they have the kool drag & drop and open/close 
jQuery feature. But they don't allow me adding stuff at a level of equal 
koolness inside. 

So is there any idea on how i could intercept meta box callbacks early 
enough to let styles & scripts get registered? I'm searching for a solution 
that avoids splitting my classes just to allow to use them not only on admin 
pages, but on meta boxes too? Or: is there any idea on where a core-patch 
should start to allow the inner life of a meta box be as kool as the box 
itself?

Thanks in advance!
K.
