Is there a reason to share the databases at all? I have many multisite instances, but I don't share the databases across any of them. Each site has its own database, so each site has its own list of enabled modules (and variables, etc.) and there is no conflict.

I have a drupal 6 multisite. I'd like each site to have a unique set of enabled modules. Is it possible for each site to have it's own unique system table? I also have unique variable tables.

'default' =>'',
'blocks'=> 'main_',
'boxes' => 'main_',
'variable' => 'main_',
'cache' => 'main_',
'system' => 'main_',

Is having unique system tables asking for trouble? I'm having problems with a couple of contributed modules like Features and environment indicator but I'm not sure the unique system table is causing the problem.
