Just a quick note, buried in same thread that Don mentioned, he outlined a  
more specific case, and this does not involve setting length to 0, but to  
any arbitrary value.

This means my approach does not help them, and although it makes sense,  
the idea that it would help Sociomantic move to D2 is not correct.
