First, this is a real post, I’m NOT a bot! Although that's exactly what a bot would say...
I did a very quick search and nothing came up so I'm posting. I'm just sharing a open source software that I just come across that you all will LOVE! Owncloud!! I have it running in a VM and as a linuxMCE/Dianemo user this would make a perfect integration into LinuxMCE or Dianemo. It's probably something that should make it onto a feature list for a future release. LinuxMCE and Dianemo both already (as far as I know) have all the minimum requirements to run it so just download, extract it to the www folder and configure it. In theory it should live and integrate just fine into LinuxMCE/Dianemo. To really make it sexy, you should modify the code of Owncloud or MCE so they use the same data structure. As a user of both systems I don't see why you couldn't just use symlinks for the OWNcloud data directory to get the job done. Also since both systems will be using the same database and owncloud is PHP based it should be really easy to intergrate the user setup process into MCE (providing you know PHP... I couldn't do it).
I'm not looking for help implementing this, I already have a rock solid stable owncloud system and I'm not going to mess with it. I've been using it for a few months now and from day one I thought this would be an awesome addition to MCE, Every day I believe more and more that this as feature you all absolutely will want!!
Once you check out the feature list and/or take owncloud for a spin I know you'll love it and agree so have fun. Google owncloud for more information. I do not work for or represent owncloud. I use it, I use linuxMCE and Dianemo, and I see an untapped potential.
