Hello Bj=F6rn,
Yes, I am interested.=20
But why do you use PHP and not Python?

This sounds _very_ interesting. Can you describe it more detailed
or even donate the code to the community?

I want to further explain it here:
The idea is to attach information about where (story filename, line#)
a Flowable object comes from to each flowable.
Then one could possibly write a function that opens the file and sets =
cursor position when clicking on an object in Acrobat Reader.
Is that possible?

I'll take a look at it.

The database itself isnt' too expensive.
10000$ per CPU license for RML in ADDITION to the thousands$ Oracle =
makes a _significant_ difference for our customers.
Now, with 3000$ it is at least worth thinking about it...
