Nope. You can have one Canvas page (apps.facebook.com/your-canvas-page) and one tab page (which can be installed on unlimited Facebook Pages) for each application.
Facebook recently updated their App configuration area, so our screenshots are a little out of date, but you can configure the canvas and page tab URLs in your FB App. Then, in JFBConnect, simply set the template you want to use for each view, and you should be good to go.
If you have any specific questions though, or think our guide is missing some info, just let us know!
Good luck,
