Yes, but from what I understand, Niels is having problem with references.

The line I gave,

>> add_action('activate_samba/loadbalancer.php', array ('LoadBalancerClass', 'installer'));

can be called _outside_ a class, at the bottom of a plugin definition file, which may or may not help.
If I remember correctly, this is how UltimateTagWarrior adds its filters and actions.
But, if you do that, you _can't_ use $this inside the registered callback functions.

Jamie.
