The easiest by far turned out to find the Fortran sources for lowess and/or 
stl from netlib (the links are also available here:
http://stat.bell-labs.com/wsc/smoothsoft.html
), and write a f2py wrapper.

If you're interested, I have a slightly modified version of lowess.f and stl.f 
(just merging the two), and the corresponding .pyf to process it. 
I'm not sure about the actual license status. If it's BSD, we could think 
about putting the fortran sources in scipy. I never really try to find an 
answer to that.
