I use a program called WP Mage which does that spinning, using ezine articles, it takes an article in English, translates it into another language and then back into English, or you can take an English language and translate it into another language and not back.
It's dirty, the words don't always read like Shakespeare, but frankly as it can spit out hundreds of articles in a matter of minutes that are sort of unique I am all about it.
You can plug in Amazon product feeds, ebay partner network feeds, Linkshare, You Tube videos, Commission Junction feeds. The caveat is you need to be approved to run the programs.
I probably haven't used it as much as I could have done, been tinkering more with datafeed sites.
Interesting though.
