For the record, Enthought is also very interested in seeing time-series 
functionality within scipy.  I'd love to see the code in the 
sandbox--coupled to the FAME api or not.  It is a sandbox, after all, 
and the refactoring can be done in the open (if you're comfortable with 
that).  To state the obvious: If it's useful, folks will pile on and it 
can get integrated into the core of scipy.  If not, it won't.

Regarding the posting of the code, we at Enthought have been involved in 
open source for a while now and my best advice is "don't do as poor a 
job as we do" in making the code available at an early stage to the 
wider community.  We're trying to do a better job of this ourselves.  
The code we've developed and open-sourced has really suffered as a 
result of our not disseminating and promoting it earlier in the process.

Best,

Travis
