Walls and Ceilings - Need Opinions: Vinyl Siding On Interior Walls

I'd like to have some opinions regarding something I'm now tossing around in my head: I have around 600 square feet of Nailite cedar shake siding. In the event people have never heard of it, it's a faux external vinyl siding, very realistic. And very expensive. Right now I have their faux glacier white stone siding on the outside of my house. Looks cool. Hell, it better look cool for what I paid for it. Cost me $240 a square. Now, I'm going to use a couple of squares of the white cottage cedar shake siding on the garage and on a wooded fence that's next to the garage. Should also look cool. After I'm done, I'll have a lot of the cedar shake siding left over. Probably about 600 square feet. I'm wondering what it would look like as paneling on the walls INSIDE my house. Any opinions?
