[Libreoffice] Howto develop an extension with URE?

Hi,

I've developed an extension to automatically load and store documents 
from/in a database. I can also start and control a slide show. This all 
works fine except some minor glitches inside libreoffice which I wanted 
to fix once my stuff is stable enough and I find some time.
For development I was using the ure and ure-devel packages from 
openSUSE. The problem now is that those packages are no longer available 
( https://bugzilla.novell.com/show_bug.cgi?id=728561 ) which leaves me 
alone in the dark. I tried to somehow get the sdk working but I failed 
generating the headers from the idl files... so my question is - how to 
use this sdk and is it safe to rely on this sdk or just switch back to 
M$ office programming + a terminal server? The M$ office solution was 
used before I managed to established openoffice/libreoffice for this 
task and now I'm a little bit puzzled if this was a good decision after 
all...

So what's the current state of ure in libreoffice?
