Is it possible to have 2 different layouts for 1 forum?

Basically what I was thinking about was this:

I would like to make a PDA friendly version of a forum while at the same time offer the same forum for PC users. The forum has a column to the left and to the right with site info in it (latest news, latest contect, tower ad) which doesn't need to be visible when using the forum thorugh a PDA ...These of course are inside the footer and header for the forum ...

Just curious if it is at all possible to get this working? If you install 2 installations of ubbthreads in 2 separate folders but both point them to use the same database - would that work ...? Even more important - would that require 2 licenses?
