 Essentially, mythfilldatabase reads in all callsigns and the iconurl 
from each source that have no icons currently set. If matches are found
it tries to download the icon and updates the channel table to point to
the new icon.

 No, "Network" in this case has nothing to do with television or the channel
name :)

 These tables are only populated if the user puts data in there, often
done with the mythfilldatabase options to import an xml icon map.
And mythfilldatabase I believe is the only part of myth that uses them
so we can manipulate the data as we like.

As well the data is only need until the icon is downloaded, once grabbed
it doesn't need to be there anymore so I'm not worried about using those
tables. I might even look into getting mythfilldatabase to import the list
using it's normal methods so we never have to actually touch the tables.

 Not asking for a feature, like you say I was just pointing out how useful 
your script is going to be for me to generate this data to be inserted into the
