Here are my thoughts.  6.x just tells me what version of drupal it works 
on. I don't take that number into account as to what features that 
module has.   The module version number tells me what version the module 
is on. Let's use CiviCRM as an example.  It has it's own version numbers 
because it is not dependent on Drupal.  Their next version is 2.1.  I 
don't expect it to be 1.1 for D6 and 2.1 for D5.

Let's use Pear as an example of a module for PHP. I don't expect pear to 
be version 1.x for PHP5 and 5.x for PHP4.
