Plugin feed software

[niuhi]

What are a list of software packages that can be purchased (or open source) for managing plugin feeds. I am looking to take content and turn it into a feed that other webmaster members areas can use. What are programs that you have used to do this? What were your expeiences with companies that provide these services...
