As someone acutely aware of some of the difficulties in what you are trying to achieve, I think you and the team have done a fantastic job. Unfortunately there are always some in our community that will find fault/issue with any path chosen. One thing you are guaranteed in this life is that you'll never have 100% of people like or agree with you, the trick I find is to not even engage. It's a fine line though... between engaging potential customers and fostering feedback and healthy discussion vs a developer "ignoring" the community.
You guys have got a tough job, I am someone following the project very closely biding my time until VR makes the feature list well into the future. There is a number of us that can see the amazing work and this project coming together, from us, you have our thanks and we cannot wait to try it.
Keep up the great work
