I have used the SWIFT package yes. For the problem I have before me it
is a little overkill :). I need to run a lot of small integrations  
with a lot of
input/output of orbits and plotting. Since code development is much  
in python I am mostly my coding in that these days, as it is  
easier to use in handling input/output of text files. Since the  
are a a little slow in pure python to be efficient I was looking for an
interface to some C/C++ integrator to speed that part up :)

I am working on some astronomy python code. Mostly orbital mechanics
with orbital determination and integration. The code is in a very early
stage of development and has a tendency of undergoing major changes
in the underlaying class structure as I add new functionality.

I have sent my reply to the list as well, in the hope that some other
orbital mechanics will be interested and chime in.
