You completely lost me here. And I thought I did understand the patent
and the fix.

what is the difference between.

short_name = rand(sid);
and
short_name = sid++;

Now if you would do
short_name = MD5(long_name);

That I understand since short_name is some function of long_name
but if I'm just inventing the short_name out of my hat. In what legal
system does it matter what is my random function I use?
