[mythtv] MythVideo Metadata

[Velorider]

I just got around to setting up a second Myth as a frontend only.   I've 
noticed that the MythVideo metadata doesn't display unless its retrieved  
from IMDB on the remote frontend.  What information I could discover from the  
mail list archive is that MythVideo is a frontend only plugin.  

For my use I  would like to import a video on any frontend and have it 
displayed on any  frontend.  I'm focused only the metadata.  I'm fine 
mounting the mythvideo  directory via NFS on all machines and placing cover 
art in the same nfs  mount.  Just like the video files are placed in a shared 
location I want the  metadata also placed in a single shared location, i.e. 
the back-end server. 

Looking into how to achieve this, Myth provides a myth protocol for the  
frontend to communicate with the backend.  My  thought is to retrieve the  
metadata over this protocol rather then from the local db.  It seems  rather 
simple, but I don't know that much about Myth and might just not  understand 
it completely.   I realize a complete solution would also stream  the video 
over the protocol, similar to MythTV. However, for now it's baby  steps.  The 
first goal would be to stream the metadata.  Then worry about  streaming the 
video file.  

So I'm asking for any feed back about the concept and any additional thoughts.
