Addendum 06/10/12 - "NASA scientists may have discovered life on Titan" See? Told ya! :-)
Addendum 10/13/11-Another article "The hazy history of Titan's air" (physorg.com)
Update: 12/31/2010 - Nice to find oneself on the bleeding edge. Here is an article quite some time after my musing:
ScienceDaily (June 7, 2010) — Two new papers based on data from NASA's Cassini spacecraft scrutinize the complex chemical activity on the surface of Saturn's moon Titan. While non-biological chemistry offers one possible explanation, some scientists believe these chemical signatures bolster the argument for a primitive, exotic form of life or precursor to life on Titan's surface. According to one theory put forth by astrobiologists, the signatures fulfill two important conditions necessary for a hypothesized "methane-based life."
