[vorbis-dev] Closed Source Releases (Ekk a LGPL problem)

Hi every one,
    I have an unfortunate need to release a closed source BeOS media codec
 for Vorbis, basically I'm using headers under an NDA so I can't release 
them.
 (Yeah I know closed source boo hiss).
So I have a couple of question about what I need to do for all this
to be above board.

I've made no changes to the libraries so thats not a problem. 

As far as I can see as  'linking a "work that uses the Library" with the 
Library
creates an executable that is a derivative of the Library '  means that
anything that links the Vorbis Libaries is covered by section 6. of the LGPL
which states I must

1) Allow modification and reverse engineering (but I don't have to make it
easy)

2) supply a copy of the LGPL and give clear notice that the libraries are 
used.

3) do one of... 

a)Include the Vorbis source code for  and the .o file for the 'work'  (so the 
headers are not revealed)
or link to these,  or verify that the users already have these.

b) used a shared library version of Vorbis (not yet an option)

c) Include Written (does this include text file) three year offer for the 
stuff metioned in a)
 

So what I want to do is 1,2 and 3a.... is that right ?...or too much or too 
to little. Or have I 
misread the LGPL.

Dave
