Well first I have the
NIH Syndrome. (only this is not the reason
)
Well in my opinion open source systems are way to complex and however they have a feature rich design, it is allmost all junk that you don't use.
I have created a content managemend system that was only one php file. It was easy and not complex, because the php code for the site and admin where stored in the database and only used when requested and not included before the system knows what to do!
further I am currently making a Control Panel for webhosting providers. I know there are software that can do this, Like Plesk, cPanel and DirectAdmin, but if you create your own software, you are free with wat you want!
In case of the web hosting cp, it will become a multi server system that works with huge clusters.
Only private CP's can that!
So we can make a wiki system with some video channels, and use the wiki as background information for the video's or something that way and with an easy code design. And we can implement every layout that we want, because we are not strict to a layout, like MediaWiki does!
And if Administrator allow it, we can even use the user database of this forum (if the admin will install some api scripts that handle that
) next to a standalone user database.
Only thing is then I must know which IPB version this forum works with.
