I have been doing this along time too, and this only applies if 
the back haul technology is asymmetrical. In many cases you are
right, because asymmetrical technology is normally leveraged to 
provide more available BW for DL since that is where the largest 
percentage of average users require it, however most servers 
have the opposite requirements. I can not remember when we have 
ever had a back bone connection that was not symmetrical, but we
have had implementations where we used asymmetrical technology 
to provide back haul for remote wireless or dialup services.
