The 'minimum' parameter and redundancy is something that should be  
dealt with in the client(s), not the driver. This is where the NSM  
approach currently breaks.

Yes. In the upsmon clients (for good reason). You don't want to do  
this in the server, let alone in the driver.

I'm afraid the latter, until we find a way how to make this  
transparent to the upsd server. Ie, let a single driver update  
multiple outlets through a single driver socket. This would be  
possible, but this would probably require quite a bit of work on the  
upsd server.
