There are two ways to do this.

One is to use bbPress itself and make a plugin that hooks new post, and then just quickly writes the info you want into plain html file somewhere that you just use file_get_contents to insert elsewhere.

The other way is to use my bbdb tool which allows you to query any of the bbpress/wordpress databases outside of bbpress by just including one file.

I think the first way is probably much easier.
