ufraw 0.17 got released on april fools day. I must say it's neat, I might stop using rawtherapee in favour of ufraw. I quickly tested it by taking an old raw that I had (of Frau Klein) and just running the raw file through a few raw converters

Picasa 3.6.0, with the default settings

ufraw 0.17, with the default settings

Rawtherapee 2.4.1, with the default neutral setting

I kinda like the Rawtherapee colours more than the ufraw ones overall, but Frau Klein looks much better in the ufraw processed image, the colours of the sky is best in the Rawtherapee image. The lens correction in ufraw certainly is useful, it's pretty automatic, I think I might shoot more raws, if only Rawtherapee had lensfun support it would be great.
