Ok - I am happy with the current method and just wrote my message 
to help making the API easier to use for the next person with a similar
problem.  But if there is no NMesh in the new version the problem
vanishes soon anyway.

Even if not helpful I learnt something by reading the answers - 
thank you :)

Is everything in the current API already working in the new 
development API?  Would it be wiser to continue working with the 
latter one?

That looks very promising :)

How about also implementing a widgets library so that Blender
could be used not only as the GUI based 3D/animation editing tool
it is now but also as a 3D/animation python extension with GUI 
and everything :)  But I think I read this already somewhere
in a document about Blenders future?

Another thing I would like to have is a method to dump
Objects / datablocks into some textual form which could be 
saved in files or a data bank or used to send objects over 
a socket.  But probably something like this exist already 
and I just don't know about it?

Sorry for those two last paragraphs which are completely
not connected to the topic of this message :)
