Now you're just trolling. You know exactly what I mean.
Maybe a bit but you are so fixated on one thing its ridiculous
There is in no way you cannot call this a hack.
It is absolutely not a hack, it is a install and configuration.
When Kodi allows you to do this from within the settings menu without having to install third party applications then we can discuss this again.
If you read my previous posts you will notice that it does allow this using UPnP.
Here is the MySQL section on the Kodi wiki.
The section starts with this notice:
http://kodi.wiki/view/MySQL
Yes because installing and managing a database is for more advanced users but the type of people that setup these environments are often used to installing databases. The kodi configuration is a few lines in a config file to tell it where to find the DB but this is a moot point if you use UPnP.
Are you using a MySQL DB with your setup (as above)? I don't see a reason why you would have to.
But anyways I am not concerned with convincing you hopefully whoever wishes to install either plex or kodi will go through the install and features docs and decide for themselves what they are comfortable with and in my opinion they are both great and capable so it comes down to preference.
