>> Raymond I think you misunderstand how MythZoneMinder works (that probably explains your previous hostility to it). It works like a client/server. MythZoneMinder the FE plugin can run on any system, it doesn't matter if it is local or remote to the system running ZoneMinder. The FE's running the plugin don't even have to be connected to the same BE. You can even access a ZoneMinder system across the internet if you wished.

It can be run on a system independent of Myth and can be compiled standalone so doesn't require any of the MythTV libs or dependencies so avoids the bloat of a full Myth install.

Yeah, mythzmserver runs on the same system as ZoneMinder and among other 
things reads the live camera images from ZMs shared memory or mmap files 
and then passes them on to the FE plugin using its own protocol for the 
communication.

It's done this way because many users who have a ZoneMinder setup use a 
separate server that doesn't have a myth BE running on it hence my 
dismay at you saying the plugin should be removed and the functionality 
added to the BE. I would have though replicating the motion detection 
stuff alone would be a major undertaking.
