As you might have noticed there is still no extension available and I kept silent about it for some time.
I started programming but I do not make as fast a progress as I planned - not due to technical difficulties but rather other factors:
Unfortunately, my customer projects have proven hardly to be as projectable as I hoped in the beginning of 2015.
As I am still a one-man-company my scope of action and the available time are extremely limited. Under these circumstances, getting a first beta ready by March or April 2015 has proven not to be feasable.
Currently it is just impossible for me to withdraw from my business and dedicate some time to MM Interactive.
The new plan calls for getting a new beta version ready by September 2015. With some luck the final version will then be ready at the same time when TYPO3 7 LTS will be ready (presumably November 2015).
