Prevent category from entering RSS feed

We are trying to expand our blog to have a news category but would like to prevent any of the posts from the cateogry entering our RSS feed. We would like to keep that feed strictly for the podcast side of the site.

Is there any way to do this? Does anyone know if there is a plugin for this?

Or, and this may be impossible, is there a way to create multiple feeds for one site with different categories in each one.

Thanks for your help!
