In the example you give here, if the events are fired from lp.client,
this code should work, since you include lp.client in the use
statement.  The publisher doesn't have to know about the subscriber.
Only that the subscriber has to know about the module publishing the
events.  I'm not actually online and working yet, but when I am, I'll
take a closer look to see why this isn't working.
