I'm interested to see this too. Co-Auth works well within the Web app but the background lockout stops any decent Excel Desktop collaboration.
I can only assume this isn't an option because of the potential complexity of the formula/data/Connections involved.

If you want co-authoring and real-time collaboration in Excel 2016 (desktop) look at http://www.xlshare.net
This is available now and there is a free version to use. There is a video on website whcih demonstrates it's capabilities.
It is very simple to use. Should take less than a minute to install and doesn't require any additional software.
