In my implementation fixed value is serving role of minv constraint and 
flex value is treated normally - as a weight. I think this makes sense.
Thus margin in between these two elements:

   <div style="height:1*; margin-bottom:20px">Hello</div>
   <div style="height:2*; margin-top:2*;">Kitty</div>

will be flexible but always greater (or equal) than 20px.
