There are a few other additional contests out there - altough AFAIK the only
reward waiting for the participants is fame:
KDD Cup 2008 - part of the KDD conference
Data Mining Cup 2008 - a competition organized by the university Chemnitz
Web Spam Challenge 2008 - part of the web spam workshop
Are there any others you are aware of?

We have code that can do it as a special case of our system. We did some
experiments as part of our last year NIPS paper which you can find here:
<http://books.nips.cc/papers/files/nips20/NIPS2007_0612.pdf>
A run on netflix took about 1 day. We did not evaluate using RMSE, though.

+1
There is still room for improvement---the algorithms that were applied in
the first progress prize weren't particularly fancy. But, good luck running
fancy algorithms on a data set of that size. And, it appears that no single
algorithm will get you to the top---as with the progress prize winners,
you'll likely need to combine 100+ algorithm outputs. I'm still anxious to
try MMMF on the data, but the Netflix data is 100x larger than the data sets
I've run MMMF on. Matlab code I have just won't cut it...

Sorry. The first year prize is gone (the $50,000 progress prize for the
first yet) and the subsequent yearly prizes are going to be very hard to get
(squeezing water from a stone). The asymptotic progress curve tells the
story.
The official contest runs "at least until October 2011.

Huh? Seems like I missed this. Could you please tell a little more about that?

The netflix contest is essentially over.
